If f(x) = 9x10 tan−1x, find f '(x).

djverab [1.8K]

Answer:

$\displaystyle f'(x) = 90x^9 \tan^{-1}(x) + \frac{9x^{10}}{x^2 + 1}$

General Formulas and Concepts:

Calculus

Differentiation

Derivatives
Derivative Notation

Derivative Property [Multiplied Constant]: $\displaystyle \frac{d}{dx} [cf(x)] = c \cdot f'(x)$

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Derivative Rule [Product Rule]: $\displaystyle \frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)$

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle f(x) = 9x^{10} \tan^{-1}(x)$

Step 2: Differentiate

[Function] Derivative Rule [Product Rule]: $\displaystyle f'(x) = \frac{d}{dx}[9x^{10}] \tan^{-1}(x) + 9x^{10} \frac{d}{dx}[\tan^{-1}(x)]$
Rewrite [Derivative Property - Multiplied Constant]: $\displaystyle f'(x) = 9 \frac{d}{dx}[x^{10}] \tan^{-1}(x) + 9x^{10} \frac{d}{dx}[\tan^{-1}(x)]$
Basic Power Rule: $\displaystyle f'(x) = 90x^9 \tan^{-1}(x) + 9x^{10} \frac{d}{dx}[\tan^{-1}(x)]$
Arctrig Derivative: $\displaystyle f'(x) = 90x^9 \tan^{-1}(x) + \frac{9x^{10}}{x^2 + 1}$

Plz help me i need it

Mila [183]

Answer: 4

Step-by-step explanation:

f(x) = 4x³ - x² + 1 g(x) = x - 1

g(2) = (2) - 1

= 1

f(1) = 4(1)³ - (1)² + 1

= 4 - 1 + 1

What is the equation of a line that is perpendicular to the given line y = 2x - 3 and

Leviafan [203]

Answer:

y = -1/2x - 1

Step-by-step explanation:

Given equation:

y = 2x - 3

Given point: (x1,y1) = (-8,3)

This is in the form of y = mx + c,

so, m1 = 2

If the lines are perpendicular then the product of their slope will be - 1 i.e.

m1 x m2 = -1

2 x m2 = -1

m2 = -1/2

Now, using one point form formula,

y - y1 = m(x - x1)

or, y - 3 = -1/2( x - (-8))

or, y-3 = -1/2(x + 8)

or, y = -1/2x - 4 + 3

or, y = -1/2x - 1

This is the required equation.
