Calculating the endpoint of a straight line, given its startpoint, length and angle

I'm presently using automation to draw in Microsoft Visio. I have the startpoint (x0, y0), the length, and the angle with the x-axis (in degrees) of a straight line. How do i calculate the endpoint (x1, y1) ?

x1 = x0  + length*cos(angle)
y1 = y0  + length*sin(angle)

Yes.... d-glitch  is absolutely right..
x1 = x0  + length*cos(angle)
y1 = y0  + length*sin(angle)

All point to  d-glitch as replied first
in case of cos/sin using radians, need to convert angle from degrees to radians :
angle = angle*PI/180 (PI=4.13152965)
