<div style="direction: ltr;font-family: Tahoma;color:
#000000;font-size: 10pt;">I was working on the computational
exercises from 371. On the first one (the one we did in class),
I can't get my solver on my ti83 to work. It seems like my x is
already set at some certain value and not a variable because I
get the same answer no matter what I put in. Do you know how to
take that value away for x so that it can be used as a variable?<br>

Excellent question. I'll explain the details behind what I am about
to tell you next week, but here is what you need to do to move on
right now.<br>
<br>
After you enter the equation in the solver, move down and set the
bounds. If I remember correctly, the bounds for this problem are
between zero and one. So on the bounds line you enter<br>
<br>
{0,1}<br>
<br>
Now, your X value, which is an initial guess at the solution, needs
to be between those two boundaries. In this case I would enter 0.5
for X and then try to solve.<br>
<br>
Let me know if you have other questions!<br>
