# How do you find the derivative of y = tan^2(x)?
We have to find the derivative of y = tan2x
### Solution
Let us differentiate using chain rule
Chain rule states that
y = f(g(x))
dy/dx= f'(g'(x)) + g'(x)
Given y = tan2x which can also be expressed as tan x2
dy/dx = 2 tan x X dy/dx(tan x)

Answer: 14 is 63.636 percent of 22
## Fastest method for calculating 14 is what percent of 22
Assume the unknown value is 'Y', and 14 of 22 can be written as:
Y = 14 / 22
By multiplying both numerator and denominator by 100 we will get:
Y = 14 / 22 x 100 / 100 = 63.636 / 100

What is the distance between (–3, –2) and (1, 4)?
Apr 19, 2018
$\sqrt{42}$
Explanation:
Work out the change in x which is $4$. This is the width. Then work out the change in y which is $6$. This is the height.
This can be used in pythgoras:
${a}^{2} + {b}^{2} = {c}^{2}$
