Question

A point moves in the plane `y` according to the law `x = A sin omegat, y = B cos omegat`, where`A,B & omega` are positive constant.
The equation for trajectroy for path taken by particle is
A. `x^(2) +y^(2) =A^(2)`
B. `(x^(2))/(A^(2)) +(y^(2))/(B^(2)) =1`
C. `y = BA`
D. `y =Ax +Bx^(2)`

Answer 1

Correct Answer - B
`sin^(2) theta +cos^(2) theta = 1`
