Question 887860: Trigonometry Given: the 2 points: pt1(X1,Y1) and pt2(X2,Y2) where pt2 is the center of a circle of radius the equal to the distance between pt1 and pt2,
Then Given: the angle theta --> pt1-pt2-pt3 ( theta is the angle between
segments pt1-pt2 and pt2-pt3 )
What are general formulae for the coordinates of P3(X?,Y?) ( not just simplified pi/2 or Npi cases )
Thanks for your input
