Rewrite the integrand:
There are multiple ways to do this integral.
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:
Let .
Then let and substitute :
The integral of a constant times a function is the constant times the integral of the function:
Let .
Then let and substitute :
The integral of is .
Now substitute back in:
So, the result is:
Now substitute back in:
Now simplify:
Add the constant of integration:
The answer is:
/ | log(sin(3*x + 5)) | cot(3*x + 5) dx = C + ----------------- | 3 /
