WebFeb 16, 2024 · Derivative by the first principle refers to using algebra to find a general expression for the slope of a curve. It is also known as the delta method. The derivative is a measure of the instantaneous rate of change, which is equal to f ′ ( x) = d y d x = lim h → 0 f ( x + h) – f ( x) h Let’s see the derivative of xsinx by using the product rule.
