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!

Use the Solve when solving for a variable and use Integration when finding area.

The Solve feature will be under the Algebra menu and the integration will be under the Calculus menu.

Here is the manual:
