pi -- 2 / | | /sin(x) \ | |------ + cos(x)| dx | \ 1 / | / 0
Integral(sin(x)/1 + cos(x), (x, 0, pi/2))
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.
But the integral is
So, the result is:
The integral of cosine is sine:
The result is:
Now simplify:
Add the constant of integration:
The answer is:
/ | | /sin(x) \ | |------ + cos(x)| dx = C - cos(x) + sin(x) | \ 1 / | /
