Hello . Your video was very helpful . I have small questions . I need to parametrise the rectangle which contains square. And rectangle moves with theta. What could be the parametric equation for this case.
yeah cartesian is just normal equations like y=2x+4 etc parametric are 'special' for the added variable making them more work to mess around with basically :)
Most people... That's how x is meant to be written. Usually to show that one is different to the other. The curly x is a value while x is the alphabet. Same way alpha is used instead of A for variables to be found.
math sounds so much nicer with a british accent

xd....ya
DDAA no everyone in England writes x as )(
Tom Drew yes it is because we write multiply as x

have my post final entrance examination of previously understood knowledge test in -0.887111 million years, thanks
incredibly helpful - thank you
amazing video, thank you
WE LOVE YOU MR HEGARTY!

@@JamBadguy top 10 questions science could not answer
isn't the cartesian form just a normal equation? what makes parametric equations so different; just the addition of a third variable?

@@emwardle5034 oh okay. lol thank you
xd...to think this video was 7 years old and the video explains everything in 7 mins!! What a coinsidence!
please write 2+sin(theta) otherwise 2 looks like a phase angle
Why is dy/dt=2t? (6mins ish) I get "t".
Isn't the chain rule f'(g(x))⋅g'(x), rather than dy/dt divided by dx/dt?
I realise this is old but when you divide by a fraction you flip it and you’ll see that the ‘dt’ terms cancel out as normal leaving dy/dx
diff form of the same thing
CHICKEN NUGGETS!!!!
Cool
5 minutes = 7 minutes . But seriously thanks for the vid

Who draws x’s like that!?

Arka Roy damn i thought x curvy was to distinguish the letter from the multiplication sign
High Voltage it is
mathy people
@DDAA we do it to differentiate the algebra x from the multiplication x
