Conclusion The derivative is a formula used to find the slope of the tangent line to a function. To find the slope of the tangent line to a function, first, find the derivative and, second, plug the corresponding x-value into the derivative. To write an equation for the tangent line, use the derivative value (the slope), and the corresponding point on the function.
