Question 1155374: i need help with writing an equation for the functions below using
Y=K+Atrig(B(x-h)) using the sine function for
amplitude -1, translation -3, phase shift -pie/4, period 2
then the same type equation using the cosine function for

amplitude -2, translation 1, phase shift -pie, period -

Y=K%2BA%2Atrig%28B%28x-h%29%29 using the sine function for
amplitude:A=+-1,
translation: K=+-3
phase shift h=-pi%2F4
period :2 => T=2pi%2FB=>2=2pi%2FB=>2B=2pi=>B=pi
Y=-3-1%2Asin%28pi%28x-%28-pi%2F4%29%29%29
Y=-3-sin%28pi%28x%2Bpi%2F4%29%29

then the same type equation using the cosine function for
amplitude: A=-2
translation:K=+1
phase shift h=-pi
period -??? I guess, I have to use-> periodicity of cos+%28x+%29 which is 2pi
P=2p => 2pi=2pi%2FB=>B=2pi%2Fpi=>B=1
Y=1-2%2Acos%281%28x-%28-pi%29%29%29+
Y=1-2cos%28x%2Bpi%29+
