$\sqrt{1+\sqrt{1+\sqrt{x}}}$ derivative | What is the derivative of $\frac{d}{dx}\sqrt{1+\sqrt{1+\sqrt{x}}}$?
Hello everyone. This lesson we will tell the derivative of $\sqrt{1+\sqrt{1+\sqrt{x}}}$.
What is the derivative of $\sqrt{1+\sqrt{1+\sqrt{x}}}$?
Compute the derivative of $\sqrt{1+\sqrt{1+\sqrt{x}}}$.
Here we have a more complicated chain of compositions, so we use the chain rule twice. At the outermost “layer” we have the function $g(x)=1+\sqrt{1+\sqrt{x}}$ plugged into $f(x)=\sqrt{x}$, so applying the chain rule once gives
$\frac{d}{dx}\sqrt{1+\sqrt{1+\sqrt{x}}}=\frac{1}{2}(1+\sqrt{1+\sqrt{x}})^{\frac{-1}{2}}.\frac{d}{dx}(1+\sqrt{1+\sqrt{x}})$
Not we need the derivative of $\sqrt{1+\sqrt{x}}$. Using the chain rule again:
$\frac{d}{dx}\sqrt{1+\sqrt{x}}=\frac{1}{2}(1+\sqrt{x})^{\frac{-1}{2}}.\frac{1}{2}x^{\frac{-1}{2}}$
So the original derivative is
$\frac{d}{dx}\sqrt{1+\sqrt{1+\sqrt{x}}}=\frac{1}{2}(1+\sqrt{1+\sqrt{x}})^{\frac{-1}{2}}.\frac{1}{2}(1+\sqrt{x})^{\frac{-1}{2}}.\frac{1}{2}x^{\frac{-1}{2}}$
=$\frac{1}{8\sqrt{x}.\sqrt{1+\sqrt{x}}.\sqrt{1+\sqrt{1+\sqrt{x}}}}$
Using the chain rule, the power rule, and the product rule, it is possible to avıid using the quotient rule entirely.

Hello everyone. This lesson we will tell the product rule for derivative.
Product Rule for Derivative

product rule of derivative |
Let f(x) and g(x) be two functions. Then the derivate of the product
$(f(x).g(x))'=f'(x)g(x)+f(x)g'(x)$
We must follow this rule religiously and not succumb to the temptation of writing $(f(x)g(x))'=f'(x)g'(x)$ ; a faulty statement.
Example:
$(x^3.e^x)'=(x^3)'.e^x+x^3(e^x)'$
=$3x^2e^x+x^3e^x$

Hello everyone. This lesson we will tell the quotient rule for derivative.
Quotient Rule for Derivative

quotient rule derivative |
Let ݂f(x) and ݃g(x) be two functions. Then the derivative of the quotient:
$(\frac{f(x)}{g(x)})'=\frac{f'(x).g(x)-f(x).g'(x)}{[g(x)]^2}$
This is how the derivative of the quotient is taken. Now let's reinforce the issue with an example.
Example:
What is the derivative of $(\frac{x^3}{e^x})'$
$(\frac{x^3}{e^x})'=\frac{(x^3)'.e^x-x^3.(e^x)'}{(e^x)^2}$
$=\frac{3x^2e^x-x^3e^x}{(e^x)^2}$
$=\frac{x^2e^2.(3-x)}{(e^x)^2}$
$=\frac{x^2(3-x)}{e^x}$
