##### Question

I thought this was very informative when you were explaining the different functions I was able to recall it very well being that i have already taken trigonometry and am now reviewing for calculus. but i was woundering if this was the complete class or if it only covers the basic ideas of trigonometry?

##### Math 104 Trigonometry Jason Rosenberry

Jason Rosenberry is an excellent teacher, has a very clear voice, and presents Trigonometry in very understandable language where one learns rather then just memorizing formulas. I give him a five stars, but it does have some problems not related to trig. The images on the screen are hard to read especially watching on an iPhone. I would prefer Jason teach from the blackboard as it is easier to see. Also, using a calculator to find trig functions of an angle is fine, but not for converting degrees and minutes to decimal. Teach how it is done without the calculator. He seems to allow students talk in class and it is annoying back ground noise.

##### Very helpful but

Frankly I depend on these lectures to self-study for my pre-calculus course. The only wish I have is to solve more exam-like problems as the ones being solved are too simple and straightforward .
