Is there a simplistic way to add, subtract, multiply or divide the comstants, pi, i and ``e''??!!!!?

Question

PLz help me, i'm wonderin' if there's an easy way to combine constants like pi,(~3.14...), E(~2.1...) & e?!!??

Answer 1

Engineers and Physicists (Experimental at least) don't bother with using any of these constants to a large number of decimal places.

Here are the most useful approximations you can easily use without too much loss of accuracy:

pi = 22/7

e (Eulers number, or natural log base) = 163/60, or for an even rougher approximation 2 21/20

I'm not sure what you are referring to for "E"

Answer 2

Most scientific calculators already have a button for pi and e. You can use these keys as a shortcut.

Answer 3

yes...program you calculator for any constants that you use often.
I often use avogadro's number (6.02x10^23) and have it programed as a function key.
