Differentiate tan inverse of x÷a<br><br>

ArbitrLikvidat [17]

Answer:

Expression Derivatives

y = tan-1(x / a) dy/dx = a / (a2 + x2)

y = cot-1(x / a) dy/dx = - a / (a2 + x2)

y = sec-1(x / a) dy/dx = a / (x (x2 - a2)1/2)

y = cosec-1(x / a) dy/dx = - a / (x (x2 - a2)1/2)

find the curved surface area and total surface area of a right circular cylinder whose height is 15 cm and the radius of the bas

otez555 [7]

Answer:

$CSA = 660cm^2$ --- Curved Surface Area

$TSA = 968cm^2$ --- Total Surface Area

Step-by-step explanation:

Given

Shape: Cylinder

$h = 15$ -- height

$r = 7$ --- radius

Solving (a): The curved surface area (CSA)

This is calculated as:

$CSA = 2\pi rh$

This gives:

$CSA = 2 * \frac{22}{7} * 7 * 15$

$CSA = 2 * 22* 15$

$CSA = 660cm^2$

Solving (b): The total surface area (TSA)

This is calculated as:

$TSA = 2\pi r(h + r)$

This gives:

$TSA = 2 * \frac{22}{7} * 7 * (15 + 7)$

$TSA = 2 * 22 * (15 + 7)$

$TSA = 2 * 22 * 22$

$TSA = 968cm^2$

mulitiply both sides of this equation by r and use the fact that r2=x2+y2 to rewrite this equation in terms of x and y r=-6sin t

tensa zangetsu [6.8K]

The equation in terms of the x and y will be 216Sin³ $\theta$ = 6x²Sin $\theta$ + 6y²Sin $\theta$ .

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The value of the expression will be given as:-

r³ = r(x² + y²)

( 6Sin $\theta$ )³ = 6Sin $\theta$ (x² + y²)

216Sin³ $\theta$ = 6x²Sin $\theta$ + 6y²Sin $\theta$

Therefore the equation in terms of the x and y will be 216Sin³ $\theta$ = 6x²Sin $\theta$ + 6y²Sin $\theta$ .
