Calculate the vertical vector component for each pair of polar coordinates.
1 | vec.y(r, v)
|
r |
A vector of numeric values representing dates in radians. |
v |
A vector of numeric values representing a uniformly sampled series of data that vary over multiple cycles. |
vec.y calculates the length of the vertical vector component of each polar coordinate pair. Given an angle r in radians and a corresponding amplitude v the vertical vector component, Vy, is calculated by:
VY(r, v) = v * sin(r)
.
Returns the length of the vertical vector component for each polar coordinate pair.
