1 / | | 3 | 2*cos (x) + 5 | ------------- dx | 2 | cos (x) | / 0
Integral((2*cos(x)^3 + 5)/cos(x)^2, (x, 0, 1))
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.
But the integral is
So, the result 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:
Now simplify:
Add the constant of integration:
The answer is:
/ | | 3 | 2*cos (x) + 5 5*sin(x) | ------------- dx = C + 2*sin(x) + -------- | 2 cos(x) | cos (x) | /
3 14*tan(1/2) 6*tan (1/2) - -------------- - -------------- 4 4 -1 + tan (1/2) -1 + tan (1/2)
=
3 14*tan(1/2) 6*tan (1/2) - -------------- - -------------- 4 4 -1 + tan (1/2) -1 + tan (1/2)
-14*tan(1/2)/(-1 + tan(1/2)^4) - 6*tan(1/2)^3/(-1 + tan(1/2)^4)
