Twice Differentiable Function


Introduction for twice differentiable function:

The twice differentiable function explains the process which takes double time differentiation on the operations of differentiation equations on the different functions like algebraic function, trigonometric functions, logarithmic functions, exponential functions etc..   In this article we are going to deal with the different functions with different variables to differentiate for the complex equations. If we have the constant in the second time differentiation then its results in the zero value.

Examples to Explain Twice Differentiable Function

Review on the twice differentiable function for the equation in the form of function f(x) = `x^2 + 3x + 10`
Solution:

The given function is f(x) = `x^2 + 3x + 10`

Differentiate the above function

`f(x)` = `2x + 3 + 0`

`f(x)` = `2x + 3`

Again differentiate (twice differentiation)  the above function f(x),

`f'(x)` = `2 + 0`

`f'(x)` = `2 `    is the required solution obtained after twice differentiation.

Review on the twice differentiable function for the equation in the form of function `f(x)` = `x^3 - x^2 + 3x + 10`
Solution:

The given function is` f(x) ` =  `x^3 - x^2 + 3x + 10`

Differentiate the above function

`f(x)` = `3x^2 - 2x + 3 + 0`

`f(x)` = `3x^2 - 2x + 3 `

Again differentiate (twice differentiation)  the above function f(x),

`f'(x)` = `6x + 2 + 0`

`f'(x)` = `6x + 2 `    is the required solution obtained after twice differentiation.

Review on the twice differentiable function for the equation in the form of function `f(x)` = `5x^2 + x^3 - x^2 + 3x + 10`
Solution:

The given function is` f(x) ` =  `5x^2 + x^3 - x^2 + 3x + 10`

This equation is rewritten as

` f(x) ` =  `x^3 + 3x^2 + 3x + 10`

Differentiate the above function

`f(x)` = `3x^2 + 6x + 3 + 0`

`f(x)` = `3x^2 + 6x + 3 `

Again differentiate (twice differentiation)  the above function f(x),

`f'(x)` = `6x + 6 + 0 `

`f'(x)` = `6x + 6 `    is the required solution obtained after twice differentiation.Understanding statistics help is always challenging for me but thanks to all math help websites to help me out.

Problems to Explain Twice Differentiable Function

Review on the twice differentiable function for the equation in the form of function f(x) = `x^2 + 3x + sin x`
Solution:

The given function is f(x) = `x^2 + 3x + sin x`

Differentiate the above function

`f(x)` = `2x + 3 + cos x`

Again differentiate (twice differentiation)  the above function f(x),

`f'(x)` = `2 + 0 - sin x`

`f'(x)` = `2 - sin x`        is the required solution obtained after twice differentiation.

Review on the twice differentiable function for the equation in the form of function f(x) = `x^2 + 3x + sin x + cos x`
Solution:

The given function is f(x) = `x^2 + 3x + sin x + cos x`

Differentiate the above function

`f(x)` = `2x + 3 + cos x - sin x`

Again differentiate (twice differentiation)  the above function f(x),

`f'(x)` = `2 + 0 - sin x - cos x`

`f'(x)` = `2 - sin x - cos x`        is the required solution obtained after twice differentiation.
