## Differentiating trigonometric function

(1) d/dx(sinx)= cosx (2) d/dx(cosx)= -sinx (3) d/dx(tanx)= -( secx)2 (4) d/dx(cotx)= -(cosecx)2 (5) d/dx(secx)= secx.tanx (6) d/dx(cosecx)= -cosecx.cotx

## Differentiating trigonometric function

d/dx(sinx)=cosx d/dx(cosx)=-sinx d/dx(tanx)=(secx)2

## Composite exponential function differentiation

When we differentiate the composite exponential function, we want to use the product rule and the chain rule.

## Second Derivative

NOTATION FOR SECOND DERIVATIVE Leibniz’s notation is d2y/dx2 Lagrange’s notation is f”

## chain rule twice

The chain rule tells us how to take the derivative of their composition. d/dx(f(g(x)))=f'(g(x)).g'(x)
