The sine of theta formula, sin(Θ) = Δy/|Δr|, /attachments/437765aa-e6cb-11e5-9770-bc764e2038f2/V2 - r.png Vector r componentscomputes the cosine of the angle between the vector r and the x axis.
INSTRUCTIONS: Enter the following:

(Δy) The y component of vector r.
(|Δr|) The magnitude of vector r

The calculator returns the sine of the angle.
