Hi
I got a TI 84 PLUS SILVER EDITION calculator
Now is there any pre programmed progra, on it to solve integrations by simply inputting the integration and limits?
Thanks
Phil
I don't know of any programs off of the top of my head for the TI-83+/Ti-84+ that can solve integrations, but
Symbolic comes pretty close, supposedly being able to find symbolic derivatives. You can try searching
http://www.ticalc.org - it probably at least has a program for the TI-83+/Ti-84+ that can find numeric integrals.
EDIT: Nevermind, just see Vladik's post.
Although I do not currently have my TI-84+ SE, integration is probably accessible from the [MATH] menu (or similar) when you graph a function. Select the "[Integral]f(x)dx" option (or similar) and select bounds. When you press [ENTER], the integral of that function with those bounds will be approximated.
If you wish to have a more precise estimate of the integral, you may wish to program the trapezoid rule or another means of numerical integration.
do you know the syntax for it? on the TI under maths theres a function: int(
But am not sure how to input the boudaries etc?
theres also another function: fnInt(
but am not sure one the syntax?
int( basically converts something to an integer that's less than or equal to the given number/list/matrix/whatever.
Heh, I forgot about fnInt( (I usually don't use my calculator to find integrals or integrals, and if I do, I use my Voyage 200, which has built-in support for symbolically finding the derivative or integral of practically anything)... fnInt( I think is kind of like nDeriv for integrals, with its syntax being: fnInt(expression,variable,lower,upper,[tolerance])
Here is an example:
fn(Int(2X,X,0,3)
(And this would return 9 as the result)
Also, note that TI provides an online manual for the TI-84+
here, which can be very useful - I use it from time to time when I'm unsure about something.
I have a question.... I need to find the integral of tan(x)/Square root (1-(sinx)^2) from pie/3 to pie/4.... I typed it in my calculator with fnInt(tan(x)/root(1-sin(x)^2,x,(pie/4),(pie/3))
What am I doing wrong it keeps saying error?
