| Try the following |
| 1. Create an expression |
|
| . Set y = 0 and solve for both exact and decimal values of x. |
| x:='x'; e1:=x->x^2+6*x-81; |
| answer1:=solve(x^2+6*x-81=0,x); answer2:=fsolve(x^2+6*x-81=0,x); |
 |
 |
 |
 |
| 2. Determine the values of x in the interval 1 x 12 that are solutions to |
 |
| = 0 eqn:=2*x^5-29*x^4-108*x^3+1611*x^2-3240*x; answer3:=solve(eqn=0,x); answer4:=fsolve(eqn=0,x,1..12); |
 |
 |
 |
| 3. Create the following function and find the value of f(cos(x)) |
| f(x) = |
 |
| y:=x^2+6*x+9; answer5:=subs(x=cos(x),y); |
 |
 |
| 4. Solve the system of equations |
| 3x + 5y - 8z = 10 |
| 2x - 8y + z = 12 |
| x - 3y + 7z = 13 |
| x:='x';y:='y';z:='z'; m1:=3*x+5*y-8*z=10; m2:=2*x-8*y+z=12; m3:=x-3*y+7*z=13; answer6:=solve({m1,m2,m3},{x,y,z}); |
