I would use the angle-difference identity on the right-hand side. This will get the away from the ....I must solve for theta2....
xsine(theta2) = L1sine(theta2 - theta1)
I don't get quite the same thing. How did you get your denominator on the right-hand side?Here's what I received as an answer. Could you please let me know if I have it correctly? I got this for the first one:
theta2 = tan-1 ( (L1 sin(theta2) / (-x + L1 cos(theta1)) )
How did you get this?? Please show your steps. Thanks!I simplified the second to be:
theta2 = theta1 + sin-1 ( (xsin(theta1)) / L2 )
