Any math question, explained.

Teotlin is an AI math tutor for school and university. Type a question and get an article or a short video at your level.

Same question, three answers.

Because “what is a derivative?” is a different question for a curious 14-year-old and a grad student studying control theory.

What is a derivative, really?

Start with average rate of change. Now shrink the interval. The derivative is what that average becomes in the limit — and here's why that limit exists…

f′(x)=lim⁡h→0f(x+h)−f(x)hf'(x) = \lim_{h \to 0} \frac{f(x+h) - f(x)}{h}
