Calculus (2) Master Needed to show steps of evaluating the integral b=0, a= pi/2 : I get stuck after applying integration by parts and simplified the negative, I get what am I supposed to do at this stage? Or did I do it wrong? Step by step is needed!

Step-by-step explanation:

We want to evaluate the integral:

Since this is a product of two functions, we can use Integration by Parts. Recall that:

Let u be t² - 3t and let dv be sin(t).

Thus:

And:

So:

Simplify:

We can use IBP once more.

Let u be 2t - 3 and let dv be cos(t). Therefore:

And:

So:

Evaluate:

Evaluate the first section:

And the second:

Therefore:
