are u miley cyrus..... :O

Answer 2

ahhhhhh

Answer 3

take the 1st equation and make t the subject

\[\frac{x}{3} = \cos(t).... then.... t = \cos^{-1}(\frac{x}{3})\]

now just substitute this into the 2nd equation for t.

Answer 4

how do i do that

Answer 5

like this

\[y = 3\sin(\cos^{-1} (\frac{x}{3}))\]

Answer 6

2.828
