Hey, I know nothing about the locus..Point P(x,y) moves so that the midpoint between P and the origin
is always a point on the circle x^2 + y^2 = 1. Find the equation of the locus of P...from Maths In Focus Ex 7.2
Thanks!
When solving a question like 3sintheta + 4costheta = 0,
how would you know which sum or difference of two angles to use?
For example, what makes you choose to use sin(theta + alpha)
instead of cos(theta + alpha)?
