1st day in calc and yeah i got a head ache right now and tired of working on it
there are two parametric equations
x=3+2cost and y=2+4sint

I need to find a way to eliminate the t either by squaring both parametric equations and subtracting or adding, substitution, elimination, etc. so I can get the equation with just x and y and graph it

thanks for all the help

Square both and add

(x-3)^2 + ((y-2)^2)/16 = 1
thanks and sorry i wrote it wrong there's a 2 in front of cost so its 2cost

Edit: thanks it doesn't really matter. same method
