How do I pass a function as an argument to another function or program?

[fb39ca4]

I am trying to make functions that calculate the Lower, Upper, and
Middle Riemann Sums and the Trapezoidal Sum of a function. How do I
pass the input function to my function? Simply typing it in as an
argument gives me a "variable not defined" error.

Can you post your function, as what you have described should work…

I commend you for your efforts and learning to program, but if you want to see what I put together, take a look at "area" on our Google Group Website

I guess from what you describe that you are using the nonCAS Nspire, and this does not support using anything with an undefined variable as the argument to a function.

What you could do is to have the user enter the function as f1(x) in the graphing screen, the only place in nonCAS that you CAN use symbolic variables. Then in your function, call f1.

With best wishes,

Steve

I'm not sure what you mean by "pass the input function to my function". What exactly is an "input function"?

Best,

Jim

In the US and Canada, there is a TI store that you can get the ac wall adapter and the rechargeable battery for $15 http://epsstore.ti.com/OA_HTML/ibeCCtpItmDspRte.jsp?section=11092&item=93907&JServSessionIdrootdlek21=b8a2z8o3d1.n6LzoN8L/AzOnMTOogTxpQOUtxCLbx0Ka0--
