A. cot 7x = (Simplify your answer.) The function is undefined. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

Explanation / Answer

sin(7pi) = 0
because sin(any integer * pi) is always ZERO

---------------------------------------------------------------

cos(7pi) :

This is an angle more than 2pi, so we can subtract 2pi three timesfrom it without changing the meaning

cos(pi) becomes -1

---------------------------------------------------------------

tan(7pi) = 0
because even for tan, tan(n*pi) = 0

--------------------------------------------------------------

cot(7pi) = 1/0

undefined
