How to calculate the point(x2,y2) with the point (x1,y1) and the angle
<p>Again i came back with a question.</p>

<p>1.I have a line drawing from a point (x2,y2) for which i do no the end point(Say point unknown as in the fig),but i knew the line length and the angle from the vector (x2,y2). Can any one help me how to calculate the unknown points.</p>
