Polar Equations to Rectangular Equations, Precalculus, Examples and Practice Problems

this one was actually so fun to do along with the video.

The goat 🐐

Instead i multiplied both sides by r getting r²=5rcosx/sin² then r²=5x/sin ²x then i multiplied both sides by sin ²x r²sin²x=5x then its easy to see that r²sin²x=(rsinx)²=y²

This is wonderful ❤❤❤❤

This is wonderful ❤❤❤❤

you are my hero 💗

slayed

one of the only reasons i’ve been improving on math is bc of this channel lmao

thanks!

Time waste, my college professors teaches more better

bro this dude is the goat

i starting learning from u since highschool didnt think i would use u for university though still using u in univetsity

YOU ARE A HERO

Holy shit super helpful

you are the greatest

R=5+cos³theta
Please solve

Nice

Thanks

goated fr fr

Why have you multiplied R^3 in last problem?? help me i don't understand

🙏👌👌👌Beautiful explanation 😊😊☺️☺️

thanks a lot!!!

you are a lifesaver. thank you so much

Final trig exam in 2.5 hours. Wasn’t totally feeling I grasped it yet. Thank you!

Thanks homie

have a test tmr and the notes didn't really help, thanks

this vid explained it so much better than my trig professor ;-;

thank you

I love you, you've saved me from so much homeworks!

waste of time

why does everyone do the easy nice round number in the examples? I'm stuck because I have r^2= 19cos theta.... my answer is (x^2-19x+y^2)r = 0 but is that even right?

I literally love you, you are so amazing. Thank you for your videos, they helped more than the lecture <3

all hail the one and only OCT

I thought x² + y² = 17??

This video was literally useless. What a waste of time.

How do I deal with this problem
3(cos 135 + isin 135)

How is 'tan(pi/4)' equal to 1 because when I type it in calculator I dnt get 1 but instead 0.01370864253 please

damn it, I studied for the test but forgot to go over these polar coordinates, surprisingly the majority of the test was these even though we just went over polar coordinates the day before. thx you good sir for the help, i probably rushed but thx to you i did pass with an average.

yes, i love the videos they help me so much with math

thank you for making this ridiculous shit somewhat easier to swallow

this channel should be called "The Life Saver"

If z=cosθ+isinθ and w=sinα+icosα. Express Z x W in the form p+qi, where p, q∈R. Hence find the maximum value of p^2+q^2
