given only f ' (x) , is it possible to find the slope of the secant for a given x_1 and x_2 without integrating?
If so how?
If so how?

A derivative is a mathematical concept that represents the rate of change of a function with respect to its input variable. It can also be thought of as the slope of a tangent line at a specific point on a curve.
To calculate a simple derivative, you first identify the function and its input variable. Then, you use the power rule, product rule, or chain rule (depending on the function) to find the derivative. Finally, you substitute the input variable into the derivative equation to get the slope at a specific point.
Derivatives have many applications in mathematics, science, and engineering. They can be used to find maximum and minimum values, determine rates of change, and solve optimization problems. In physics, they are used to model motion and describe the behavior of physical systems.
A derivative represents the rate of change of a function, while an antiderivative represents the original function before it was differentiated. In other words, taking the derivative of a function gives you its slope, and taking the antiderivative of a function gives you the original function (up to a constant).
One example of a simple derivative is finding the derivative of the function f(x) = x^2. Using the power rule, we get f'(x) = 2x. So, the slope of the tangent line at any point on the parabola y = x^2 is twice the x-coordinate of that point.
