Question 36:
The question asks to evaluate the integral:

\int \text{قتا}(س+ب) \text{ظتا}(س+ب) \,ds

Recall the standard integral for $\text{قتا}(x)\text{ظتا}(x)$ .
We know that the derivative of $\text{قتا}(x)$ is $-\text{قتا}(x)\text{ظتا}(x)$ .
Therefore, the integral of $\text{قتا}(x)\text{ظتا}(x)$ is $-\text{قتا}(x) + C$ .
Apply this to the given integral.
In this case, the argument is $(
