## exponential function Posted by: Rahulakumar S on Mar 31, 2018

applying both the product rule and chain rule.

## chain rule Posted by: Rahulakumar S on Mar 31, 2018

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

## Quotient rule Posted by: Rahulakumar S on Mar 31, 2018

The quotient tells us how to find derivative of the quotient of two functions. d/dx(f(x)/g(x))=d/dx(f(x)).g(x)-f(x).d/dx(g(x))/(g(x))2

## product rule Posted by: Rahulakumar S on Mar 31, 2018

product rule :(f(x)g(x))’=f(x)g'(x)+g(x)f'(x) differentiating trigonometric functions: d/dx(sin(x))=cos(x), d/dx(cos(x)=-sin(x) differentiating logarithmic function: d/dx(ln(x))=1/x

## product rule Posted by: Rahulakumar S on Mar 31, 2018

Product rule (f(x)g(x))’=f(x)g'(x)+g(x)f'(x) Differentiating Exponential function d/dx(ex)=ex

## product rule Posted by: Rahulakumar S on Mar 31, 2018

The product rule tells us how to find the derivative of the product of two functions. d/dx(f(x)g(x))=f(x)d/dx(g(x))+g(x)d/dx(f(x))

## power rule Posted by: Rahulakumar S on Mar 30, 2018

Differentiating negative power the power rule also allows us to differentiate expressions like 1/x2

## power rule Posted by: Rahulakumar S on Mar 29, 2018

The power rule says that if n is a real number, the derivative of xn = nxn-1
