You can put this solution on YOUR website! What is the smallest positive value for s where y=sin2x reaches its maximum?
a. pie over 4
b. pie
c. 3pie over 2
d. 2pie
e. 5pie over 2
---------------------
The sine is a max at pi/2 (pi, the Greek letter, not pie, the dessert).
If 2x = pi/2, then x = pi/4 ( = 45º)
-----------------------------------
I think you meant to say x, not s.
