Maths Query on 2 vectors and its angle

[smartwhiz]

i know (x1,y1), (x2,y2) and the angle... how can i find (x3,y3)... help wud be appreciated

keepin in mind that the distance between the (x1,y1) and (x2,y2) is equal to (x2,y2) and (x3,y3)

What about google? Google find alot about this terms.

for example:

Code: Select all

core::vector2df vector(x1, y1);
vector.rotateBy(angle, vector2df(x2, y2)); // where angle is anticlockwise in degrees
// vector is now == x3, y3
