# Integration Formulas PDF

Integration Formulas PDF: Integration can be considered as the reverse process of differentiation or can be called Inverse Differentiation. Integration is the process of finding a function with its derivative. An integral is a function, of which a given function is the derivative. Integration is basically used to find the areas of the two-dimensional region and computing volumes of three-dimensional objects.

## Integral Formulas PDF

The list of integral formulas are,

• ∫ 1 dx = x + C
• ∫ a dx = ax+ C
• ∫ xn dx = ((xn+1)/(n+1))+C ; n≠1
• ∫ sin x dx = – cos x + C
• ∫ cos x dx = sin x + C
• ∫ sec2 dx = tan x + C
• ∫ csc2 dx = -cot x + C
• ∫ sec x (tan x) dx = sec x + C
• ∫ csc x ( cot x) dx = – csc x + C
• ∫ (1/x) dx = ln |x| + C
• ∫ ex dx = ex+ C
• ∫ ax dx = (ax/ln a) + C ; a>0,  a≠1
