pi -- 3 / | | (cos(x) - 1/2) dx | / -pi ---- 3
Integral(cos(x) - 1/2, (x, -pi/3, pi/3))
Integrate term-by-term:
The integral of cosine is sine:
The integral of a constant is the constant times the variable of integration:
The result is:
Add the constant of integration:
The answer is:
/ | x | (cos(x) - 1/2) dx = C - - + sin(x) | 2 /
___ pi \/ 3 - -- 3
=
___ pi \/ 3 - -- 3
sqrt(3) - pi/3
