Question 988011: Please help me with this problem also:
Sketch the sinusoid y+=+-2+%2B+3+sin+%28x+%2B+Pi%2F2%29

You can put this solution on YOUR website!
y+=+-2+%2B+3+sin+%28x+%2B+Pi%2F2%29+
Here's the plot:
+graph%28+600%2C+400%2C+-14%2C+14%2C+-6%2C+2%2C+-2+%2B+3%2Asin%28+x+%2B+pi%2F2+%29%29+
Note that everywhere +y+=+0+, +sin%28+x+%2B+pi%2F2+%29+=+2%2F3+
Note that when +x+=+0+%2B-+2%2Api+ , +y+=+1+
