I was just going through Chapter 4 - Basic Computations from the User Manual. I have a worksheet in Documenet mode where I put in the commands I see as I go through the Chapter.
I reached the part about using solve. I didn't know it was so easy to use the context menu to do things like solve numerically, use solve, etc. I typed in the equation x^3+2x-9=0 and tried a few of these options for solve. Many gave the answer 1.762496376, which is the real root.
Now, eventually, I wanted to see the two additional complex roots. But I never did.
Then I simply added a new line to the worksheet, copied over the equation, and tried the option solve directly. Now I see three solutions.
Next, I added yet another line and executed solve(x^3+2x-9=0) and got three solutions again.
What I don't understand is why the first line, even now, doesn't ever return the three solutions. I choose solve from the menu but it only returns the real root 1.762496376.
Here is the exact worksheet I am using: 4_-_Basic_Computations.mw
There is a text in bold that says Solving Equations and Inequations and the problematic command is on the line after that.
(once again, I was not able to insert the worksheet contents here, would also like to know why this never works for me).
