In the following, u, v, w are functions of x; a, b, c, n are constants [restricted if indicated]; e=2.71828... is the natural base of logarithms; In u is the natural loraithm of u [i.e. the loraithm to the base e] where it is assumed thad u>0 and all angles are in radians.

What is derivative of $sec^{-1} x^2$?
$Sec^{-1} u$ derivative formulas:
$\frac{d}{dx}sec^{-1} u=\frac{1}{|u|.\sqrt{u^2-1}}.\frac{du}{dx}$
Now let's answer our question.
Differentiate $y=sec^{-1} x^2$
Solution For $x^2$ > 1 > 0,
>>> $\frac{dy}{dx}=\frac{1}{|x|\sqrt{(x^2)^2-1}}.\frac{d}{dx}x^2$
>>> $=\frac{2x}{x^2\sqrt{x^4-1}}=\frac{2}{x.\sqrt{x^4-1}}$
Answer = $\frac{2}{x.\sqrt{x^4-1}}$

4-x^2 graph | What is the graph of $4-x^2$
You can reach 4-x^2 graph in the below.
Graph of $4-x^2$
$y=4-x^2$ graphics:
A parabola that opens down is said to be “concave down”. The point (0, 4) is known as the vertex.
Coordinate Points :
x,y = (0,4)
x,y = (1,3)
x,y = (-1,3)
x,y = (2,0)
x,y = (-2,0)
x,y = (3,-5)
x,y = (-3,-5)

What is the slope of the tangent of f(x) at the point =1 ?
$f(x)=(x^2-4)^3$
Solution:
Derivative of f(x):
$f'(x)=[(x^2-4)^3]'$
$=3.(x^2-4)^2.(x^2-4)'$
$=3.(x^2-4)^2.2x$
$=6x.(x^2-4)^2$
At point x=1, the slope of the tangent of the function f is
$f'(1)=6.(1).(1^2-4)^2=6(1).(-3)^2=54$
Derivative of $(x^2-4)^3$ | Find the derivative of the function $f(x)=(x^2-4)^3$
Solution
We need to derive the composite function $u^3$, where $u=x^2-4$. Consequently, we need to use the chain derivative.
$f'(x)=[(x^2-4)^3]'$
$=3.(x^2-4)^2.(x^2-4)'$
$=3.(x^2-4)^2.2x$
$=6x.(x^2-4)^2$
