Hi, I'm trying to lern wxMaxima and I have the following parametric equations: W(w):=[a*w,b*w,c*w]; (%o1) W(w):=[a*w,b*w,c*w] V(v):=[d*v,e*v,g*v]; (%o2) V(v):=[d*v,e*v,g*v] P(w,v):=[x,y,z]+W(w)+V(v); (%o3) P(w,v):=[x,y,z]+W(w)+V(v) P(w,v)=[1,2,3]; (%o4) [a*w+d*v+1,b*w+e*v+2,c*w+g*v+3]=[1,2,3] but when I try to solve the follwing example, I get no solution: solve([P(w,v)=[1,2,3]],[w,v]); [] Why?? thanks for any advice :-)
