Derivative as the Slope of a Tangent?
Yes, the derivative of an equation is the slope of a line tangent to the graph.
What is an increment on a graph?

Derivative of zero?
The derivate of zero - as well as the derivative of ANY constant (non-variable) number, is zero. (A graph of y = 0 for example will be a horizontal line - the slope is zero.)
How can sketch a graph of a derivative?
To sketch a graph of a derivative, first look at the points where your original function f(x) has any horizontal tangents. If is does at that horizontal tangent plot a point correspondingly on the x-axis. From here analyze your functions in intervals. Where the f(x) function is increasing, your derivative function f prime of x should always be above the x axis, and conversely, where f(x) is decreasing your derivative function should always be below the axis As a crucial step, you should look at locations within the original function that are endpoints, cusps. and undefined points. This is essential as the derivative of the function will be undefined at those locations, and must be shown clearly on the graph (which is usually resolved with an open circle). To best understand sketching derivatives, try experimenting with a derivative plotter (java applet that can usually be found on-line for free. Also try to imagine the tangents to the original graph, as the graph progresses. Lastly, it should be noted that the magnitude of your derivative will depend on the rate of change of the function. However, most calculus teachers will let this be arbitrary.
What is the difference between nonlinear and linear functions?
Linear function:No variable appears in the function to any power other than 1.A periodic input produces no new frequencies in the output.The function's first derivative is a number; second derivative is zero.The graph of the function is a straight line.Non-linear function:A variable appears in the function to a power other than 1.A periodic function at the input produces new frequencies in the output.The function's first derivative is a function; second derivative is not zero.The graph of the function is not a straight line.
