Hi,
This is probably a silly question but i'm new to SAGE and was
wondering if SAGE is able to solve symbolic equations by eliminating
variables - similar to MAPLEs eliminate command.Here is what i'm
trying to solve:
eqn_x = - x - a3 cos(theta1) sin(theta2) + d3 cos(theta1) cos(theta2)+
d2sin(theta1)
eqn_y = - y - a3 sin(theta1) sin(theta2) + d3 sin(theta1) cos(theta2)
- d2cos(theta1)
eqn_z = - z + d3 sin(theta2) + a3 cos(theta2)
i'm trying to solve for d3 by eliminating theta1 and theta2 , this is
how it can be done in MAPLE:
eliminate({eqn_x,eqn_y},theta1)
eq_1 := %[2][1]
eliminate({eqn_z,eq_1},theta2)
eq_2 = %[2][1]
and from there it is fairly simple to figure out the next steps and
get d3
i've tried various combinations of solve, simplify and trigsimp(from
maxima) and other such functions but it doesnt seem to eliminate
variables.....any ideas?
thanks in advance!
