Question

Given the point `P(8/17, 15/17)`, how do you find `sintheta` and `costheta`?

Answer 1

`sin t = 15/17`
`cos t = 8/17`

Explanation:

Point P (8/17, 15/17) is located on Quadrant I of the unit circle with diameter R = 1.
Right triangle formula:
`R^2 = (8^2 + 15^2)/289 = 289/289 = 1` --> R = 1
There for, by definition of the trig functions sin x and cos x -->
`sin t = 15/17`
`cos t = 8/17`
