Homework Statement
Sketch the graph of y = sinx(1-cosx) over [-2pi, 2pi]
Homework Equations
first derivative and second derivative
The Attempt at a Solution
y' = cosxsinx
0 = cosxsinx
x = pi/2, 3pi/2, 0, pi, 2pi
I know I have the sin values right (the answers say the same) but the cos values in the answers are actually 2pi/3 for MAX and 4pi/3 for MIN. For that cosx would have to equal -1/2. I'm not sure how to get that );
Thank you!
