Urgent help in finding out a point on a line
This is my scenario.
I have a line and I know that it is originating at x1,y1.
I also know the angle of the line with respect to the base.
Given a distance from the x1,y1 I need to know the other points x2,y2
How do I do this.
can anyone help me with providing a formula say
x2= so and so
y2 = so and so
I've to use this in a computer language and so would be glad if I could get a formula such as the above.
Please guys help needed.
Thanks in advance.
