Answer 2

For Non-Tangent functions we can't take its derivative.

• Derivatives are defined only for the graphs which looks like straight lines
• If slope exists for a function then there exists a derivative.
• Mod function,floor function,Ceil function are the examples where derivative exists.
• Integration and derivatives are complement to each other but they are reversible on any functions.
