Question

convert to cartesian equation
x = 3 sin t, y = 5 cos(2t)

Answer 1

hint:\[\cos(2t)=2\cos^2t-1\]

Answer 2

there is the hints^

Answer 3

use the fact that:\[y=5\cos (2t)=5(1-2\sin ^2(t))\]and that:\[x=3\sin t\Longrightarrow \frac{x}{3}=\sin (t)\]substitute that value of sine in the equation above it.
