Question 47889: I tried to figure out the period of the following functions can you tell me if they are correct?
"find the period of the following functions"
a.) y=4sin%282x%29%2B1
period: 180?
b.) y=-3tan(pix)
period: 2?
c.) y=cos%5E2%28x%29
period: 180?
d.) y=-3sec(-6x)+2
period: -60?
if not can you help me with the correct answer? thank you.

You can put this solution on YOUR website!
a.) y=4sin%282x%29%2B1
period: 180 degrees
graph%28600%2C600%2C-10%2C10%2C-10%2C10%2C4%2Asin%282x%29%2B1%2C1%29
b.) y=-3tan(pix)
period: 1

c.) y=cos%5E2%28x%29
period: 180 degrees
graph%28600%2C600%2C-10%2C10%2C-10%2C10%2Ccos%28x%29%5E2%29
d.) y=-3sec(-6x)+2
period: pi/3
This one seems to be a symmetry graph.
