Derivative of csc(x) = $\frac{d}{dx} [csc(x)] = -csc(x)cot(x)$

Step-by-step explanation:

Step 1: Define

$\frac{d}{dx} [csc(x)]\\x = \frac{3 \pi}{2}$

Step 2: Differentiate

Differentiate: $\frac{d}{dx} [csc(x)] = -csc(x)cot(x)$

Step 3: Evaluate

Substitute in x: $-csc(\frac{3 \pi}{2} )cot(\frac{3 \pi}{2} )$
Evaluate: $0$

F(x)=2(x)^2+5 sqrt (x+2) f(0)

krek1111 [17]

F(0) = replace every x with 0

$2 ({0})^{2} + 5 \sqrt{0 + 2} \\ = 2 + 5 \sqrt{2}$
=9.0710678119
=9.07

Step-by-step explanation:

The mode is the data value that appears most often

5,7,9,5,18,6,8,5

Arranging the data from smallest to largest

5,5,5,6,7,8,9,18

The number that appears most often is 5

This is the smallest value of the data
