Derivative Calculator – Formula, Free Online Tools, Mobile Apps & FAQs for South Africans
What Is a Derivative Calculator?
A derivative calculator is a tool that calculates the derivative of a function. In South Africa, this tool can be particularly useful for students studying mathematics, engineers, economists, and anyone dealing with complex functions on a regular basis. For example, it can help determine the rate of change in specific applications like engineering projects, financial analysis, or scientific research.
How to Calculate Derivatives Manually
The formula used to calculate a derivative is based on the slope of a curve at a given point. Mathematically, the derivative of a function f(x) is denoted as f'(x) or dy/dx. To calculate the derivative of a function, you can use first principles by finding the limit of the difference quotient.
For example, if you have the function f(x) = 2x^2, to find the derivative, you would use the formula f'(x) = lim(h→0) [(f(x+h) – f(x))/h] and simplify the expression.
