For the following equation, graph y = f1(x) and y = f2(x) on the same screen on your calculator. From the graphs, make a conjecture as to whether the equation is an identity. If so, prove your conjecture.tan x + cot x = 2 csc 2x
What will be an ideal response?
The statement is an identity. The student's answer should include a proof.
