RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

If you came here looking
for advice in the stock market, you landed on a page for the wrong type of derivative. However, if you came
looking for information on the kind of derivatives used in calculus, then here you go.

There are of course an infinite number of derivatives, but the ones I have listed here are some of the most common. The derivative is basically the dual of the integral. Integrating the derivative of a function yields a scaled version of the original function. To be mathematically correct, it is necessary to add an unknown constant to the integrated result form because it evaluates to zero when the derivative is taken.

Sound confusing? It really isn't. If I integrate the function ∫ x dx, the answer is x^{2} + c. If I then differentiate d/dx x^{2}
+ c, I get x/2 + 0. So, the scaling factor is 1/2 in this case; it could be 1 or anything else depending on the
function.
