Took Trigonometry over the summer and Matthew Cotter made the class so easy understand. I aced everything until we got to identities. This was ultimately my downfall and I believe it was due to my lack of effort. All in all, he understood where we were coming from as students and worked with us. Best teacher I've had yet in college.

He's a young professor but he's a bit out of touch with how to entertain a class. If you're not a stud at math, i recommend taking a different professor. When he lectures, I kind of get the vibe like "you should already know this" from him. Not my favorite. His tests are 75 points with about 13 questions so if you miss two you're at a B already!!

Prof. Cotter was awesome. He's super passionate about what he teaches, knows the material well, does a great job at explaining everything and answers everybody's questions. Doing the homework helps reinforce the material and is a great way to study for tests. Not difficult, but do have to put in effort to succeed, as with any math class.

Passing his class, even getting an A in his class DOES NOT, by a long shot mean you'll be ready for the next course. He skips so much material because it's "too hard" and if you take calc 2 with a different professor, you're screwed. He avoids explaining things because it's "too difficult" so he does examples and expects you to regurgitate on exam

Avoid Cotter if you can. He has the best intentions to teaching Math courses, but he is just honestly bad at it. He can be condescending in lecture and very rarely answers questions concisely. He doesn't require attendance, but you'll want to be there for each lecture because he has a very particular way of doing things. Grade is completely tests.

Went to his office hrs. Asked him if he could explain a concept but he was busy so instead just gave me his laptop to look at the hw. He missed two of his other office hrs (even after email) and on my 4th visit he came in, put his stuff down, then walked out to get lunch.

I transferred to UC Davis after taking him for Calc 1 and 2. His lectures are usually easy to follow and his passion for math was really inspiring. Best of all, he is considerably easier than similar teachers (i.e. skips curve sketching in Calc 1 and doesn't require you to know exactly when to use each integration technique in Calc 2).

Had Mr Cotter for Math 150 summer online course. Mr Cotter's teaching style is super easy to follow along with and learn from, even over zoom. The best you could hope for from standard lecture-style teaching. Just pay attention. He had a family emergency halfway through the course and still managed to finish the class, big respect to him for that.

Took calc1 with Prof. Cotter online during the summer and he is the best! He is pretty strict with grading because he wants you to gain a sense of professionalism but he is the best at teaching calc. You can tell he really loves teaching and that he's passionate about it. He always makes sure you understand the material during class.

Had Cotter for Calc 2 and Calc 3, he helped me so much and I found that he was the best professor for me in math. I had a C in Calc 1 but got an A in Calc 2 as well as a high B in Calc 3. He was super helpful during office hours and just made time for you to understand the lectures. Wish he could be my professor for other math classes.

Honestly the best math teacher I've taken. He makes hard concepts easy to understand like he's some kind of wizard or something. His lectures are God sent. So straightforward and easy to comprehend. His view is forward thinking, and his tests are exactly like the homework. This should be your #1 choice for a good teacher.

He makes things so easy to understand bc he writes the course himself. His teaching style takes a little getting used to, but I love his thoroughness as he will show you the "twists"/variations of every single calc problem that will be on the Hw/test. If you can, use an iPad & Apple Pencil/stylus for the class. Makes stem classes sooo much easier.

Cotter is in my opinion an excellent prof. His lectures are incredibly well organized, his homework reinforces the concepts found in the notes very well. There are almost no situations where you need outside resources (Chegg, textbook youtube). Tests match up to lecture and homework well. Responds to emails incredibly quickly. You can do it!

Professor Cotter is very lecture heavy, with a light homework load. The test questions are taken directly from class notes and homework. He grades your hw on neatness and structure which can take some adjustment however in the long run it definitely helps with organization. Lastly he consistently emphasizes the importance/value of mathematics.

I love Professor Cotter, most clear professor I have had. The first two tests were not a problem but third test onwards was when it got drastically hard. You need to ensure that your study habits can ensure a smooth transition from dead easy to really hard but his lecture and homework clearly follows the tests. Highly recommend!

If you're a math major- he's the class to take. Lectures are mandatory (though he records them)- TAKE LOTS OF NOTES. The examples mirror the homework extremely well. He's extremely passionate about math, to the point where it actually freaks me out a little bit. If that's not your cup of tea, find someone else.

Calculus is a complex subject, but Cotter is difficult. He provides you with most of the tools you need to thrive in his class, except when you ask for help. He is one of those stem professors who degrades you for asking for clarification (yells at you or tells you to look at the lectures to not repeat himself). Be sure to ask on a good day.

A GREAT math instructor. He explains things very well! Be sure to do the homework as you learn each section because its a lot. I did everything last min and I have a low B. 4 homework assignments (due day of test), 4 tests, 4 quizzes. He records his lectures! Tbh it's not bad just study in advance.

His lectures are all recorded so its helpful to go back and rewatch. But be prepared to watch a lot outside of class as he often misses and and posts a makeup lecture. Also calc 3 starts off really easy but then it all piles up in the end so stay on track with hw and use to study.

Free textbook given for class but not used or needed as the Professor's lectures are amazing. Homework assignments are not due weekly. Multiple assignments are turned in the day of major tests which gives flexibility. Must apply yourself to pass. Combines traditional learning with new age technology.

Prof. Cotter is really nice and you can tell he's very passionate about math and teaching. He misses class quite frequently, which I would have no problem with if he provided a make-up lecture, but sometimes he doesn't because he tries to cram it in the following lecture. This caused the class to ramp up in material near the end.

VERY passionate about math. Tends to go on rambles and teaches at a slower pace, but that makes it a bit easier to catch up on work if you fall behind. If you take notes and understand what is going on in the lecture and homework, you will be fine. Pre-calc is a hard course but Cotter makes it as easy to digest as possible.

He makes everything simple and easy to understand. His exams are great because he tells us exactly what kinds of questions will be on them and how many. Only thing is he grades homework a bit harshly which is kind of annoying but other than that 10/10 guy and chill. Although there's no extra credit so what you get is what you get.

2-3 hour long lectures on zoom that are recycled from Covid time. His canvas organization is horrible. Has his own calendar pdf you are expected to follow instead of placing it in a week to week showcase of what is to do like every other professor does. His discussions only last a day so good luck on replying to two classmates.

Explains topics very well, makes Calc easy. Tests are very similar to HW so never any surprises. Very picky on structure. I've gotten everything right on tests but been marked down to a 90 because of "format". Like every test he finds something wrong with your format. But, this is a very easy class if you just know how to do the HW problems.
