Hi!

Imagine that we have an equation like:

Y+X=10 and wants us to make the Y of the subject, at this case this is the easy answer:

Y=10-X.

So what I'm basically saying is, how do you do that by using the cal? for more complex equations?

so how do you convert this Y+X=10 to Y=10-X using the calculator?

And the other question asks:

use graphic calculator to calculate the area bounded by the curves Y=3x+2 and Y=e^x-1?

how do we find area bonded using ti-89?

Many thanks!
