1 / | | (x + 5)*acot(x) dx | / 0
Integral((x + 5)*acot(x), (x, 0, 1))
Rewrite the integrand:
Integrate term-by-term:
Don't know the steps in finding this integral.
But the integral is
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 result is:
Add the constant of integration:
The answer is:
/ / 2\ 2 | x acot(x) 5*log\1 + x / x *acot(x) | (x + 5)*acot(x) dx = C + - + ------- + ------------- + ---------- + 5*x*acot(x) | 2 2 2 2 /
1 5*log(2) 5*pi - + -------- + ---- 2 2 4
=
1 5*log(2) 5*pi - + -------- + ---- 2 2 4
1/2 + 5*log(2)/2 + 5*pi/4
