Integral(sin(x)*cos(x)/(sin(x)^2) + 1, (x, 0, 1))
Integrate term-by-term:
There are multiple ways to do this integral.
Let .
Then let and substitute :
The integral of is .
Now substitute back in:
Let .
Then let and substitute :
The integral of a constant times a function is the constant times the integral of the function:
The integral of is .
So, the result is:
Now substitute back in:
The integral of a constant is the constant times the variable of integration:
The result is:
Add the constant of integration:
The answer is:
/ | | /sin(x)*cos(x) \ | |------------- + 1| dx = C + x + log(sin(x)) | | 2 | | \ sin (x) / | /
