pi -- 3 / | | 4*cos(x) dx | / -pi ---- 3
Integral(4*cos(x), (x, -pi/3, pi/3))
The integral of a constant times a function is the constant times the integral of the function:
The integral of cosine is sine:
So, the result is:
Add the constant of integration:
The answer is:
/ | | 4*cos(x) dx = C + 4*sin(x) | /
