Find dy/dx any one x=acost , y=asint​

Mathematics
1 answer:
dangina [55]2 years ago
8 0

Answer:

x=a \cos t \implies \dfrac{dx}{dt}=-a \sin t

y= a \sin t \implies \dfrac{dy}{dt}=a \cos t

Using the chain rule:

\begin{aligned}\implies \dfrac{dy}{dx} & =\dfrac{dy}{dt} \times \dfrac{dt}{dx}\\\\& = a \cos t \times \dfrac{1}{-a \sin t}\\\\& = \dfrac{a \cos t}{-a \sin t}\\\\& = - \dfrac{\cos t}{\sin t}\\\\& = - \cot t\end{aligned}

A cylinder has a radius of 8 meters and a height of 4 meters. .
Novay_Z [31]
<h2><u>Solution</u> :-</h2>

Given : Radius of cylinder = 8 m

Height = 4 m

Volume of cylinder = πr²h cu. units

= 22/7 × 8 × 8 × 4 m³

= 804.57 m³ (approx.)

Curved surface area = 2πrh sq. units

= 2 × 22/7 × 8 × 4 m²

= 201.14 m² (approx.)

Total surface area = 2πr(r + h) sq. units

= 2 × 22/7 × 8 (8 + 4) m²

= 2 × 22/7 × 8 × 12 m²

= 603.43 (approx.)

Hey there :)

3 ( 2t + 1 )
We use what is called the distributive property to get rid of the parenthesis

We multiply the term outside the parenthesis by all terms inside
3 ( 2t ) + 3 ( 1 )

6t + 3 → Your answer

Explain how the sum and difference formula cos(A+/- B) = cosA cosB -/+ sinA sinB could be useful?
serg [7]
One way it's useful is in the application of phasors in physics. Phasors require you to add up vectors of two different angles, so the cosine angle addition formula can be used if you already know the cosine and sine of the original vector angles.
