Question about Texas Instruments TI-89 Calculator
How do you store a number, say like the point of intersection as A, B, C, D...
and every time when i type in xsin(x^2), the calculator tells me it's undefined variables. and when i try to integrate it on the home screen, the calculator can't process the function either.
The calculator is very sophisticated but it does not solve all problems. In particular it does not know (does not have) the Integration by parts algorithm. But you can always have a numerical value of a definite integral.
To store a number in any variable
You enter the number 18[STO->][Alpha]A stores 18 in A.
My opinion is that you cannot take advantage of the functionalities of this calculator if you do not take some time to consult the manual. You do not have to read the whole thing, just read the chapter or the exemples that show you how to handle your current question (whatever it may be.)
Hope it helps.
