1 / | | sin(x) | ----------- dx | 2 | 4 - cos (x) | / 0
Integral(sin(x)/(4 - cos(x)^2), (x, 0, 1))
Rewrite the integrand:
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:
Add the constant of integration:
The answer is:
/ | | sin(x) log(2 + cos(x)) log(-2 + cos(x)) | ----------- dx = C - --------------- + ---------------- | 2 4 4 | 4 - cos (x) | /
log(2 + cos(1)) log(3) log(2 - cos(1)) - --------------- + ------ + --------------- 4 4 4
=
log(2 + cos(1)) log(3) log(2 - cos(1)) - --------------- + ------ + --------------- 4 4 4
-log(2 + cos(1))/4 + log(3)/4 + log(2 - cos(1))/4
