Question

Evaluate ∫
2
−1y2+y−2dy

Answer 1

Answer:

2y - ⅓y³ + ½y²- 2y

Step-by-step explanation:

This is a question on integration.

Given that the signs are addition and subtraction the integration is simple.

We can integrate them bit by bit.

This means we integrate them separately one at a time.

Integrate (2 - y²+ y - 2) dy

We integrate this as follows :

= 2y - ⅓y³ + ½y² - 2y

This is the integral of the given equation.
