Equation Solving Capabilities
- Single equations
- solve(3*x^2-2*x+1=0,x);
- solve(tan(x)=1.5);
- solve(exp(-x^2)=x);
- Multiple equations
- solve({x^2+y=0, x + y^2 = 1},{x,y});
- evalf(");
- eq1 := x + 2*y + z = -7; eq2 := 2*x + y - z = 0; eq3 := 3*x + a*y + z = 1;
- solve({eq1,eq2,eq3},{x,y,z});
- a := 4; #now re-enter "solve"
