Integration :

the literal meaning of integration is summation.

comparison between differentiation & indefinite integration:

• operations of differentiation integration and define on functions
• the process of differentiation integration are reverse of each other.

↪ integration is reverse process of differentiation

example

d(secx)dX = secx tanx

and ∫secx tanx dx = secx+ c

question :

∫cos x dx

since cosx is the differentiation of sin x.

therefore ;

∫cos x dx = sinx + c ...(1)

the result can be verified by differentiating the expression on the right side of equation (1).
