Hi guys,
I have done what I can with the following:
Given a parametric curve x = xsint, y = sin(2t) where t is in R.
Find an implicit equation of this curve.
MY ANSWER:
y = 2costsint = costx
Therefore sint = x/2, cost = y/x
sin^2(t) + cos^2(t) = x^2 / 4 + y^2 / x^2 = 1
Would this be right?
I understand that x != 0 but why can't I just multiply every value underlined by 4x^2?
Thank you, any input is appreciated!
