Question 856222: Hello. I am to write the sinusoidal equation and sketch graph for Max=95 min=40, P=24
so far I have P=2pi/b 24=2pi/b equaling pi/12 as period
Then amplitude 90-40/2 A=25 Vertical shift is 90+40/2 65
y=25sin(pi/12)(x)+ 65
But I can't seem to make this work, questioning it all. Thanks

You can put this solution on YOUR website!
You said max was 95 so why are you using 90.
A=%2895-40%29%2F2=%2855%2F2%29
Your constant is then B=%2895%2B40%29%2F2=135%2F2
y=%2855%2F2%29sin%28%28pi%2F12%29x%29%2B135%2F2
