Few things which we have covered
What is Integration?
Basic Formulae
Special Variable
Actual Substitution
Integration by parts

Definite Integration
Properties of Definite Integration
What is Integration?
Integration is reverse of Differentiation
ex-
Symbol
∫x2dx
Integration of a constant-
∫ a dx =∫a.x0 dx
∫ 7 dx =
Addition & Subtraction to a constant-
3+k
3-k
Example-
∫(√x +1/√x)dx
(a) 2x1/2(1/3 x-1)
(b) 2x1/2(1/3 x+1)
(c) 2(1/3x + x1/2)
(d) None of these.
Evaluate = ∫5x2 dx :
(a) 5/3x3+ k (b) 5x3/3+k (c) 5x3 (d) none of these
Integration of 3 – 2x – x4 will become
(a) – x2 – x5 / 5 (b) 3x - x2 - x5 /5+ k (c) 3x -x2 +x5/5 +k (d) none of these
Given f(x) = 4x3 + 3x2 – 2x + 5 and ∫ f(x) dx is
(a) x4 + x3 – x2 + 5x (b) x4 + x3 – x2 + 5x + k
(c) 12x2 + 6x – 2x2 (d) none of these
Special Variables-
This is applied when by taking a linear function of x i.e ax or ax+b as X , we can apply any of the standard formulae
Here we apply standard formula and divide the answer with derivative of ax+b i.e a
Use method of substitution to integrate the function f(x)=(4x+5)6 and the answer is
(a) 1/28(4x+5)7+k
(b) (4x+5)7/7+k
(c) (4x+5)7/7
(d) none of these
Integrate (x+a)n and the result will be
(a) (x+a)n+1/n+1 + k
(b) (x+a)n+1/n+1
(c) (x+a)n+1
(d) none of these
Method of Substitution or Change of Variable-
Substitution
When we have a function & it’s derivatives
∫ (5x2+4x+3)4 (10x+4)dx
Note - Trick to identify which one is function & which is derivative
Evaluate: ∫dx/√(x2+a2)
(a) 1/2 - log (x+√x2+a2) + C
(b) log (x+√x2+a2) +C
(C) log (x √x2+a2)+ C
(d) 1/2log (x √x2+a2)+ C
Square Partial Integration-
Using method of partial fraction to evaluate
∫ (x+5) dx/(x +1) (x + 2)2 we get
(a) 4 log (x + 1) - 4log(x + 2)+3/x+2+k
(b) 4 log (x + 2) – 3/x +2)+k
(c) 4 log (x + 1) – 4 log(x+2)
(d) none of these
Special Substitution-
∫d( x2+1) / √x2+2 is equal to
(a) x/2 (√x2 +2)+k
(b) √x2 +2 +k
(c) 1/(x2+2)3/2 +k
(d) none of these
Definite Integration-
The value of ∫(1+logx)/x dx is:[Given Loge =1]
(a) 1/2
(b) 3/2
(c) 1
(d) 5/2
