Maths AS HELP!!

Can someone briefly tell me when do we use differentiation, integration, and normal equation? I get really confused no matter how much I solve past papers >.<

 

[Igcse giver]

differentiation is used when they ask to find out the gradient. dy/dx is the gradient of a given point in equation
Integration is used when dy/dx is given and asked to find the equation
Integration is also used to find the area under the curve so u integrate the equation
Integration is also used when volume is asked to find. but then u square the whole equation and take pie as common

That really helped! Thank you so much! :'D
Just one more question, when shall I use the perpendicular gradient and when should I use the normal gradient? I'm so sorry for asking more questions ;__;

 

[Igcse giver]

when they ask for the equation of tangent to the curve its gradient will be the normal dy/dx of the equation of curve

if they ask for normals equation then first find dy/dx normally then divide it by -1 to get the gradient of normal i.e. the perpendicular gradient
