Question #da001

Answer 1

`sintheta=+-sqrt(1-p^2)`
`tantheta=(+-sqrt(1-p^2))/p`

Explanation:

`"given " costheta=p`

`rArrsintheta=+-sqrt(1-cos^2theta)`

`color(white)(rArrsintheta)=+-sqrt(1-p^2)`

`"the sign is dependent on which quadrant " theta" is in"`

`tantheta=(sintheta)/(costheta)`

`rArrtantheta=(+-sqrt(1-p^2))/p`
