Trigonometry (Continued)
Summary - 1. In the principle value branches, the following formulae holds: sin -1 (sin x) = x, cos -1 (cos x) = x, tan -1 (tan x) = x, cos -1 (cot x) = x, sec -1 (secx) = x, cosec -1 (cosecx) = x 2. If a is some constant angle, then - sin q = sin a q = n p + (-1) n a , n Z - cos q = cos ..

Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Tutor Vista tutor helped me understand and gave me some practices and showed me how to do them.
This tutoring impressed me a lot! not only did the tutors helped me with currect lessions i needed help with, but they prepared me for future trig lessons to come and very useful imformation - gabriella
I think the tutors knew their stuff really well and was very helpful. math was actually something I dread.not anymore ,Thank you Tutor Vista - jennifer,New york
