Undergrad F(x) = sin(-3x) increase decrease intervals
Yes, thank you. I have already solved it this way. My textbook had an error in the solutions sheet. They just solved the double inequality and did not exchange the increase and decrease intervals. -

Undergrad F(x) = sin(-3x) increase decrease intervals
How would you use sin(x) = -sin(x) in this problem? -

Undergrad F(x) = sin(-3x) increase decrease intervals
Hi everyone. Could anyone help me solve this. I need to find the increase and decrease intervals of f(x) = sin(-3x). The increase intervals of sin(x) are -\pi/2 + 2\pi*k < x < \pi/2 + 2\pi*k Is the following the right way to solve my problem (for increase intervals)? -\pi/2 + 2\pi*k < -3x <...
