Question #2c359

1 Answer

Jun 6, 2017

$sin (- x)$ $sin(-x)$ is an odd function

Explanation:

A function is even iff $f (- x) = f (x)$ $f(-x)=f(x)$

$sin 45 \neq sin (- 45)$ $sin45!=sin(-45)$ so $sin (- x)$ $sin(-x)$ is not even

A function is odd iff $f (- x) = - f (x)$ $f(-x)=-f(x)$

$sin 45 = - sin (- 45)$ $sin45=-sin(-45)$ therefore $sin (- x)$ $sin(-x)$ is odd
