Derivative of sum function
WebNow, the derivative is linear, so that the derivative of a sum is the sum of the derivatives, which allows putting the derivative inside the sum. Also linearity says that the derivative of the product of a constant by a function is the constant times the derivative of the function. This allows to write the following: $$\frac{d}{dx}g(x)=\sum_{i ...

WebThus, the derivative of a sum is just the sum of the derivatives. Example 1 Find the derivative of 9.8x2 +5x. Solution Since we have already calculated the derivatives of the individuals terms, we can simply apply the sum rule for derivatives. The derivative of the first term is 19.6x and the second is a linear function so its derivative is 5. WebThe Derivative tells us the slope of a function at any point. There are rules we can …
WebJan 29, 2024 · Example 1: Find the derivative of f (x) = 4x + 2 Solution: Using the Sum Rule, we know that the derivative of a sum of functions is equal to the sum of the derivatives of each function. In this case, the function can be written as f (x) = 4x + 2. Using the constant rule, the derivative of the constant 2 is 0. The derivative of 4x is 4.
