Where can I find tutorials on how the programs on ti-calculators work?

I was wondering where can I find more advanced stuff on ti-calc programs and how existing functions work. For example, how does the derivative and integral function work exactly? More of practical stuff, less of useless games and trick programs.Where can I find tutorials on how the programs on ti-calculators work?
Uhh, if you have a ti-83 or 84, just hit math 8 for derivative and math 9 for integrals. for derivatives put in the function, then a comma, then the variable you used in the equation (likely X) then a comma, then the point you want the slope at. For integrals, enter the function, then a comma, then variable you used in the function (likely x), then a comma, then the smaller number you want the area under, then a comma, then the larger number you would like. I hope that helps because I don't know of a tutorial, You could always just look at your manual =)Where can I find tutorials on how the programs on ti-calculators work?

Well, if you have a TI-83, then you can have the calculator figure out the integral or derivative at a certain point:


Press Math and then scroll down. You should see FnInt( and nderiv( . FnInt is the integration, and deriv is the derivative. The derivative is the slope of the tangent line, while the integral is the area under the curve.
This should help:
