Question

The function y= 3sin(2x) is:


the inverse of a secant function

undefined as x=2π

even ( f(x) = f(-x) for all x)

odd ( f(-x) = -f(-x) for all x)

neither even nor odd

Answer 1

Odd.

Answer 2

\[\sin ^{-1}x \neq \sec x\] (sec x is the reciprocal of cosx not the inverse of sinx)

I don't think sin x is undefined at 2pi...

sinx is not even (\[\sin(-x) \neq \sin(x)\] for all x)

However, sin IS odd (sin(-x) = -sin(-x) for all x)

Answer 3

the function is odd?
