I tried using "FindRoot" in Mathematica 7 but it says "solutions don't converge, perturb the initial values". I tried many set of initial values but none worked.

Is there a way to solve this??

cos(t_3)*l_3*cos(t_1)*cos(t_2)-cos(t_3)*l_3*sin(t_1)*cos(a_1)*sin(t_2)+sin(t_1)*sin(a_1)*sin(t_3)*l_3+cos(t_1)*l_1+l_7+cos(t_7)*l_6=0

cos(t_3)*l_3*cos(t_1)*cos(a_1)*sin(t_2)+cos(t_3)*l_3*sin(t_1)*cos(t_2)+sin(t_1)*l_1-cos(t_1)*sin(a_1)*sin(t_3)*l_3-sin(t_7)*cos(a_7)*l_6+s_7*sin(a_7)=0

sin(a_1)*sin(t_2)*cos(t_3)*l_3+cos(a_1)*sin(t_3)*l_3+sin(t_7)*sin(a_7)*l_6+s_7*cos(a_7)+s_1=0
