Hi Bilal - I assume you mean the part where I write 1/3 as x/3x. The reason I do this is to add 1/3x and 1/3 together (and to do this you must use cross multiplication or putting them both over a common denominator). It is not a necessary step to solve the problem, but it makes the answer look a little nicer :-)

Hi Jack, I dont understand why you multiplied both sides by x

Would the order still matter in case of odd number of power? For example: y=t^3 or t^5? In those cases I wouldnt need to worry about + and -

Hi, could you please do an example where there are trig functions in the parametric equations, I swear you need to use the identities but I'm not sure about when/how. Thanks!
