## CHSE Odisha Class 12 Math Solutions Chapter 9 Integration Exercise 9(i)

Evaluate the following Integrals.

Question 1.

I = \(\int_1^3\)5x^{2} dx

Solution:

Here a = 1, b = 3, f(x) = 5x^{2}

⇒ nh = b – a = 3 – 1 = 2

Question 2.

I = \(\int_{-1}^1\)ex dx

Solution:

Here a = -1, b = 1, f(x) = x, nh = b – a = 2

Question 3.

I = \(\int_0^6\)x dx

Solution:

Here a = 0, b = 6, f(x) =x, nh = b – a = b

Question 4.

I = \(\int_0^4\)(x^{2} + 2x + 4) dx

Solution:

Here a = 0, b = 4, f(x) = x^{2} + 2x + 4 and nh = b – a = 4
