Which equation in rectangular form describes the parametric equations x=2-3 cos t and y=1+4 sin t?

liraira [26]

Answer:

The parametric equations represents an ellipse by the rectangular equation $\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1$ .

Step-by-step explanation:

We proceed to use the following trigonometric identity to derive an expression in rectangular form:

$\cos^{2} t + \sin^{2} t = 1$ (1)

Where:

$\cos t = \frac{2-x}{3}$ and $\sin t = \frac{y-1}{4}$

Then, we expand the expression as follows:

$\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1$ (2)

The parametric equations represents an ellipse by the rectangular equation $\frac{(x-2)^{2}}{9} + \frac{(y-1)^{2}}{16} = 1$ .

$\mathsf \purple{ - ( \frac{y}{x} )}$

$\mathsf \purple{ - ( \frac{ - 4}{5})}$

$\mathsf \purple{( \frac{4}{5} )}$

$\mathcal\blue{METHOD\:2}$

$\mathsf\purple{m\:=\:(Y2\:-\:Y1)\:÷\:(X2\:-X1)}$

$\mathsf\purple{m\:=\:(-4\:-0)\:÷\:(0\:-\:5)}$

$\mathsf\purple{( \frac{4}{5})}$

$\mathcal\blue{METHOD\:3}$

$\mathsf\purple{m\:=\:rise\:÷\:run}$

$\mathsf\purple{m\:=\:( \frac{4}{5})}$

$\mathbb\pink{NOTE:}$

The difference between the y-coordinates of the two points is called the rise.
The difference between the x-coordinates of the same two points is called the run.
The slope can be calculated by dividing the rise by run.

What are the best study tips

exis [7]

1. Get a snack next to you so you dont spend most time saying your hungry.
2. Make a comfortable spot. (not too comfortable or you will fall asleep)
3. Start with the first concepts and get harder as you finish.
4. Practice 6 or more problems/questions per lesson.
5. NO T.V. OR ELECTRONICS OR MUSIC because they are distracting.
6. Make notes to your self by repeating the concept. Repetition helps you remember.
