Questions tagged [wolfram-language]

Wolfram Language is a knowledge based, multi-paradigm programming language. In a first approximation, the Wolfram Language = Mathematica + Wolfram|Alpha + Cloud + more. It's compatible with Mathematica, but it's a significant evolution, including knowledge, deployment and many new ideas.

This tag should be used on questions that pertain to the Wolfram Language created by Wolfram Research.

The Language's homepage can be found here: http://www.wolfram.com/language/

Programs can be written in the language via the wolfram programming cloud: https://programming.wolframcloud.com/app/

Wolfram Mathematica is returning an incorrect derivative for the function (16x-4^x)/2x

In Mathematica, I open a new notebook and define the function f(x) as: f[x_]=((16x-4^x)/2x) Then, I calculate the derivative with the command: f'[x] This returns the following: 1/2 (-4^x + 16 x) + 1/2 x (16 - 4^x Log[4]) I believe this answer to be…
