You can put this solution on YOUR website!
Here's the plot:
+graph%28+500%2C+400%2C+-7%2C+7%2C+-2.5%2C+2.5%2C+sin%28x%29+%2B+cos%282x%29+%29+
Here's the separate functions
+graph%28+500%2C+400%2C+-7%2C+7%2C+-2.5%2C+2.5%2C+sin%28x%29%2C+cos%282x%29+%29+
Just figure where pi/2, pi, 3pi/2, 2pi are
Hope this helps
