Even \u0026 Odd Functions Integral Shortcut
Even \u0026 Odd Functions Integral Shortcut

Property 1 :

Integration is independent of change of variables provided the limits of integration remain the same.

Property 2 :

If the limits of definite integral are interchanged, then the value of integral changes its sign only.

Property 3 :

Property 4 :

Property 5 :

If f(x) is integrable on a closed interval containing the three numbers a, b and c, then regardless of the order of a, b and c.

Property 6 :

Property 7 :

Property 8 :

To check if the function is odd or even, in the given function f(x) apply x = -x

Evaluate the following problems using properties of integration.

Question 1 :

The given function is odd.

Question 2 :

The given function is odd.

Question 3 :

Question 4 :

The function f(x) is even.

Question 5 :

The function f(x) is even.

= 1 – (1/2) [-1/3+1]

= 1-(1/2)[2/3]

= 1-(1/3)

= 2/3

Question 6 :

The function f(x) is odd.

Question 7 :

2I = 0

I = 0

Question 8 :

Question 9 :

Question 10 :
