WTF do we do if our HW problems are a billion times more complex than this? If anyone can help me solve something like: x=cos(5t) , y=sin(2t) and get a Cartesian Equation out of it I would be EXTREMELY grateful!
@@Tryinglittleleg nah man. I looked the problem up elsewhere and they said to just plug in numbers to get the graph. The specific problem I was doing didn't ask for the equation itself. I just wanted to know if I was doing something wrong.
i think its just the convention. we usually deal with x and y terms so removing any unfamiliar variables allows us to deal with less parameters. so rather than dealing with x,y and t, we only have x and y.
lmao everyone criticizing his mistakes when they know damn well he saved them last minute
ON GOD YO LMFAO
A lot of them aren’t even mistakes, just preference 😂 like stfu he isn’t your weak ass professor and he’s saving your ass what more do you want 🤣
2:54 This is why x^2+y^2=r^2 is the equation of a circle.
Thank you for a very helpful, free lesson 🙏
after 6 years Thank you.
This really helped me, thank you!
It is supposed to be (-4) not (+4)
yeh i saw that
7:02
I wish you would turn it to y = f(x) form
thx man, u really helped me out
cheerz
How do you approach an trigonometrical equation with two parameters? (t and s)
Thank you :)
-4 not +4

same
Did you figure it out?

try using double angles for y=sin2t (y=2 sint cost), not sure about cos5t though sorry
@@sydneybestfeeds yea the double angle is obvious to me but how on earth do you handle cos5t in trying to change this to a cartesian equation ?
I am so confused with the cartesian equations. Why does it exist in the first place? Is it just to make me suffer!!!

It exists to make you suffer and fail in life and makes you homeless
@@Elitea20 Thanks
@@lucasvic7010 don’t worry I literally have my actually exam tomorrow so I’m abit screwed
@@Elitea20 I will have my test too on monday
Thank you very much!!
great video!! :)
very useful thanks
What about when t is an exponent?
You can bring it down using natural log
y=x^x+3x-4 not y=x^2+3x+4 8:20
Thanks
I'm ab to take my final haha
10:12 can't we simplify this further
I dont understand a thing he said.
it means that you have brain problem
thank you very much!!!
