Those terms were created dynamically, of course, and they're already at a minimum (yes, I know it doesn't look very much like it). I'm using the regular solve() command. 2011-05-31 23:02:21 -0500 asked a question Unable to make sense of Maxima expression Hey everybody, I'm trying to do some symbolic calculations. When trying to solve the following equation set for v_0, v_1, w_0, and w_1, I get "TypeError: Unable to make sense of Maxima expression". The equations are added below: v_0 == 1/6*(2*(s0_0 + s1_0 + s2_0)*t0_1 + 2*(s0_0 + s1_0 + s2_0)*t1_1 - 3*((t0_0 + t1_0)*t1_1 + t0_0*t0_1 + t0_1*t1_0)*w_0 - sqrt(-18*(t0_1^4 - 2*t0_1^3*t1_1 + 2*t0_1^2*t1_1^2 - 2*t0_1*t1_1^3 + t1_1^4)*w_1^2 - 9*(t0_0^2*t0_1^2 - 2*t0_0*t0_1^2*t1_0 + t0_1^2*t1_0^2 + (t0_0^2 - 2*t0_0*t1_0 + t1_0^2)*t1_1^2 + 2*(t0_0^2*t0_1 - 2*t0_0*t0_1*t1_0 + t0_1*t1_0^2)*t1_1)*w_0^2 - 8*((s0_1 + s1_1)*s2_1 + (s0_0 + s1_0)*s2_0 - s0_0^2 + s0_0*s1_0 - s0_1^2 + s0_1*s1_1 - s1_0^2 - s1_1^2 - s2_0^2 - s2_1^2)*t0_1^2 - 16*((s0_1 + s1_1)*s2_1 + (s0_0 + s1_0)*s2_0 - s0_0^2 + s0_0*s1_0 - s0_1^2 + s0_1*s1_1 - s1_0^2 - s1_1^2 - s2_0^2 - s2_1^2)*t0_1*t1_1 - 8*((s0_1 + s1_1)*s2_1 + (s0_0 + s1_0)*s2_0 - s0_0^2 + s0_0*s1_0 - s0_1^2 + s0_1*s1_1 - s1_0^2 - s1_1^2 - s2_0^2 - s2_1^2)*t1_1^2))/(t0_1 + t1_1) v_1 == -1/3*(3*(t0_1^2 + t1_1^2)*w_1 - (s0_1 + s1_1 + s2_1)*t0_1 - (s0_1 + s1_1 + s2_1)*t1_1)/(t0_1 + t1_1), w_0 == -1/6*(3*(t0_0*t0_1 + t0_1*t1_0)*t1_1*v_0 - ((s0_0 + s1_0 + s2_0)*t0_0*t0_1 + (s0_0 + s1_0 + s2_0)*t0_1*t1_0)*t1_1 + sqrt((2*(s0_1 + s1_1)*s2_1 + s0_1^2 + 2*s0_1*s1_1 + s1_1^2 + s2_1^2)*t0_0*t0_1^3*t1_0*t1_1 + (2*(s0_1 + s1_1)*s2_1 + s0_1^2 + 2*s0_1*s1_1 + s1_1^2 + s2_1^2)*t0_0*t0_1*t1_0*t1_1^3 + 9*(t0_0^2*t0_1^2 - 2*t0_0*t0_1^2*t1_0 + t0_1^2*t1_0^2)*t1_1^2*v_0^2 - 6*((s0_0 + s1_0 + s2_0)*t0_0^2*t0_1^2 - 2*(s0_0 + s1_0 + s2_0)*t0_0*t0_1^2*t1_0 + (s0_0 + s1_0 + s2_0)*t0_1^2*t1_0^2)*t1_1^2*v_0 + ((2*(s0_0 + s1_0)*s2_0 + s0_0^2 + 2*s0_0*s1_0 + s1_0^2 + s2_0^2)*t0_0^2*t0_1^2 + (2*(s0_0 + s1_0)*s2_0 + s0_0^2 + 2*s0_0*s1_0 + s1_0^2 + s2_0^2)*t0_1^2*t1_0^2 + 2*(2*(s0_1 + s1_1)*s2_1 + 2*(s0_0 + s1_0)*s2_0 - 5*s0_0^2 + 2*s0_0*s1_0 - 5*s0_1^2 + 2*s0_1*s1_1 - 5*s1_0^2 - 5*s1_1^2 - 5*s2_0^2 - 5*s2_1^2)*t0_0*t0_1^2*t1_0)*t1_1^2 + 9*(t0_0*t0_1^3*t1_0*t1_1 - 2*t0_0*t0_1^2*t1_0*t1_1^2 + t0_0*t0_1*t1_0*t1_1^3)*v_1^2 - 6*((s0_1 + s1_1 + s2_1)*t0_0*t0_1^3*t1_0*t1_1 - 2*(s0_1 + s1_1 + s2_1)*t0_0*t0_1^2*t1_0*t1_1^2 + (s0_1 + s1_1 + s2_1)*t0_0*t0_1*t1_0*t1_1^3)*v_1))/(t0_0*t0_1*t1_0*t1_1) w_1 == -1/6*(3*(t0_1 + t1_1)*v_1 - (s0_1 + s1_1 + s2_1)*t0_1 - (s0_1 + s1_1 + s2_1)*t1_1)/(t0_1*t1_1)]  And the exact error is: TypeError: unable to make sense of Maxima expression '[If(and(-pi/2
