5*pi ---- 6 / | | (cos(x) + 3) dx | / 0
Integral(cos(x) + 3, (x, 0, 5*pi/6))
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:
/ | | (cos(x) + 3) dx = C + 3*x + sin(x) | /
1 5*pi - + ---- 2 2
=
1 5*pi - + ---- 2 2
1/2 + 5*pi/2
