1) Select the numeric solver by pressing the ORANGE shift key followed by the 7 key.
2) Select the polynomial solver (press 3) to solve for the zeroes of a polynomials.
3) Once in the Solver, I select EDIT which takes me to a type of matrix editor.
4) I enter [ 1. 0. 2. 0. 2. ] for this polynomial X^4+2X^2+2
5) Select ENTER and am taken back to the Solver.
6) Arrow down for Roots and select SOLVE which give me the roots.
Since I can't see the solution, the tutorial suggests to select EDIT which takes me back to the matrix writer. I scroll through the entires in the matrix to see each of the 4 solutions but still can't see the whole solution.
I try to select +MID and MID+ to change the size but still can't see the solutions.
I have a Casio 991EX where I have a button S<->D which will put a long solution on two lines so I can see it. Does the 50G do anything similar?
Also, when I solve it in the Prime, the Prime lets me scroll to the right seeing all the solutions.
[-0.455089860562-1.09868411347*i,-0.455089860562+1.09868411347*i,0.455089860562-1.09868411347*i,0.455089860562+1.09868411347*i]
I tried brickviking's suggestion of using VIEW but that's not letting me see the solutions, either.
I haven't tried John H Meyers "page by page viewer" because I figure there must be a way to accomplish my task without getting side tracked on having to figure out how to enter programs into the 50G (I'm still new to all this).
Thanks,
Jim
1) After obtaining the solution, press PRG(left shift EVAL)->TYPE->OBJ->
This removes the"roots" tag.
2)Then DROP and do OBJ-> again and you get all four roots neatly displayed on stack levels 2 through 5 with the element count on level 1.
You don't really need a program to do this.
