<div>
Thanks could you help me with this though its <br />
just i need a way to do this <br />
so for example the user chooses the following (1) ( sin a) &nbsp;( cos a) and then this is applied so that <br />
b = B1(1) + B2(sin a) + B3(cos a) where i have to solve for B1 B2 B3 so its a system of matrix equataions could you help me with logic of how to do this?

Elaborate more, what are B!,B2 &amp;&nbsp;B3.<br />
Can you post whole problem statment

hi I was wondering if somebody could givew me a few pointers as to how a i could implements a calculator in java <br />
I have to be able to take in some data in file format<br />
a b<br />
1 2<br />
3 2<br />
.<br />
.<br />
.<br />
1 6<br />
and processes it by the application of functions as chosen by the user from a button panel.<br />

Java calculator

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Java

An algorithm is a self-contained step-by-step set of operations to be performed. Algorithms exist that perform calculation, data processing, and automated reasoning. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, eventually producing "output" and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input.
