## exponential function

y=v(u(x)) — dy/dx=v'(u(x)).u'(x) (1) d/dx(sinx)=cosx (2) d/dx(cosx)=-sinx (3) d/dx(tanx)=(secx)2

## Differentiating related function

d/dt(sinx(t))=d/dx(sinx).dx/dt d/dt(cosy(t))=d/dy(cosy).dy/dt

## Parametric functions differentiation

In general, to find the derivative of a function defined parametrically by the equations x=u(t), y=v(t), we use the following rule dy/dx=(dy/dt).(dt/dx)=v(t)/u(t)

## Second Derivative parametric function

x=u(t) dx/dt=U'(t) y=v(t) dy/dt=v'(t) dy/dx=dy/dt.dt/dx d2y/dx2=d/dt(dy/dx).dt/dx

## Negative power differentiation

We can rewrite each rational term in the expression as a negative power of x

## Derivatives of inverse trigonometric function

the formula for the derivative of arctan(x)=1/(1+x2).

## Implicit differentiation

In implicit differentiation, we differentiate both sides of the equation according to x and treat y as an implicit function of x
