Answer 1

Is this equal to zero?

Answer 2

yes the answer is (pi)+12/2 and 12-(p)/2

Answer 3

I dont know how to get to the answer though

Answer 4

\[6+\frac{\pi}{2}\cos(\frac{\pi x}{4})=0\]

Answer 5

is the above written correctly?
\[\frac{\pi}{2} \cos(\frac{ \pi x}{4})=-6\]
\[\cos( \frac{\pi x}{4})=\frac{-12}{\pi}\]

Answer 6

YES THANK YOU
I just realised that all i need to do is |amplitude|+vertical translation
