## anonymous one year ago BEST ANSWER REWARDED:WRITE THE EQUATION OF THE SIN FUNCTION :AMPLITUDE 3 , PERIOD PI/4

1. anonymous

amplitude is 3, put a 3 out front

2. anonymous

so something like $3\sin(bx)$

3. anonymous

to find $$b$$, the period of $$\sin(bx)$$ is always $$\frac{2\pi}{b}$$ set $\frac{2\pi}{b}=\frac{\pi}{4}$ and solve for $$b$$

4. anonymous

ok and how do u solve for b? cross multiply? can you demonstrate @satellite73
