I was looking at a robotics kinematics analysis & there is one geometric equation assumed in the analysis which I can't seem to understand. I have a simplified diagram above.
In the above diagram
AC = a1
BC = a2
AB = x1
AX = x2
CX is perpendicular to AB
From here, how does one get to
x2 = (a1^2 - a2^2 + x1^2)/(2 * x1)
