Integral(1/(2*sin(x) - cos(x) + 3), (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:
Now simplify:
Add the constant of integration:
The answer is:
/ /x pi\ | |- - --| | 1 |2 2 | / /x\\ | --------------------- dx = C + pi*floor|------| + atan|1 + 2*tan|-|| | 2*sin(x) - cos(x) + 3 \ pi / \ \2// | /
pi - -- + atan(1 + 2*tan(1/2)) 4
=
pi - -- + atan(1 + 2*tan(1/2)) 4
-pi/4 + atan(1 + 2*tan(1/2))
