QUESTION: Dear Deirdre

http://en.wikipedia.org/wiki/Scientific_calculator

http://www.math.com/students/calculators/source/scientific.htm

http://www.squarebox.co.uk/scalc.htm

Can there be further enhancements to the Scientific Calculator device functions in addition to the current functions provided by the Device ?

For examples : Matrix Algebra, Computing real roots of quadratic equation, Simultaneous equations, Vector algebra etc

Awaiting your reply,

Thanks & Regards,

Prashant S Akerkar

ANSWER: Most modern calculators have these capabilities built-in. Others are programmable, and you can write a program to do these functions if they aren't already part of the calculator's functions.

But for an example, here is a video of a TI-89 calculator being used to solve systems of equations. http://www.youtube.com/watch?v=CcUkZFuQ9Jc

And most calculators today can deal with not only real, but imaginary numbers as well. Most people just don't fully read the manuals and are unaware of their capabilities. Here is a TI article describing the use of matrices to solve simultaneous equations. http://www.youtube.com/watch?v=CcUkZFuQ9Jc

The same calculator has vector capabilities as described here: http://www.tc3.edu/instruct/sbrown/ti83/vecprod.htm

Do all modern calculators also have physical and chemical constants

useful in physics, chemistry formulas ?

Awaiting your reply,

There are many types of modern calculators, all with different features and functions. Most will have pi and e, some will have other constants. HP has a list of the constants on their model 30S here: http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&dlc=en&docname=bpia5092
