How to calculate next coordinate in this problem?

[fredand44]

Hello guys!

I'm programing a small app in Java.
The app needs to draw a line between two coordinates.

The given values I got:
coordinate_1 = x1,y1
the angel for the line = a
the length of the line = l

Is there a way to find out coordinate_2 = x2,y2?

Best regards
Fredrik

One 'standard form' for a line is
y = y₀ + tan(\(\displaystyle \alpha\)) (x - x₀)
where \(\displaystyle \alpha\) is the angle of the line relative to a line parallel to the x axis, positive anti-clockwise as measured from the 'positive side'.
