Integral((cos(x) + 18*sin(x))/(3*sin(x) - 4*cos(x)), (x, 0, pi/2))
There are multiple ways to do this integral.
Rewrite the integrand:
The integral of a constant times a function is the constant times the integral of the function:
Rewrite the integrand:
Integrate term-by-term:
The integral of a constant times a function is the constant times the integral of the function:
Don't know the steps in finding this integral.
