Derivative of a sum
WebThe derivative of a function describes the function's instantaneous rate of change at a certain point. Another common interpretation is that the derivative gives us the slope of the line tangent to the function's graph at that point. Learn how we define the derivative using limits. Learn about a bunch of very useful rules (like the power, product, and quotient … WebTo take the derivative of a sum, you break apart the sum into single expressions, take the derivatives, and add them. Suppose we have a sum f (x)+g (x). To take its derivative, we take the derivative of f (x) and g (x) individually, and them take the sum. Mathematically: d/dx [f (x)+g (x)] =d/dx [f (x)]+d/dx [g (x)] =f^’ (x)+g' (x)
