As the locators get close enough, the slope gets closer to the slope of the tangent line, which is the value of the derivative of the function at the point. A Normal Bell Curve calculates a grading curve from a comparison of student results. Get the free "Parametric equation solver and plotter" widget for your website, blog, Wordpress, Blogger, or iGoogle. First, we calculate the learning curve factor b = ln(p)/ln(2) = ln(0.75)/ln(2) = -0.415. The slope of a curve refers to its steepness indicating the rate at which it moves upwards or downwards. In the unit on Slope, we talked about measuring the slope of a straight line.Now we will discuss how to find the slope of a point on a curve. One of the differences between the slope of a straight line and the slope of a curve is that the slope of a straight line is constant, while the slope of a curve changes from point to point.. As you should recall, to find the slope of a line you need to: Note: A small test population with a minimal difference between the highest score and the lowest score will not result in an effective Bell Curve scale. You can find the slope of a curve with the TI-84 Plus calculator, even though it is not equipped to find the derivative of a function. But you can’t calculate that slope with the algebra slope formula because no matter what other point on the parabola you use with (7, 0) to plug into the formula, you’ll get a slope that’s steeper or less steep than the precise slope of 3 at (7, 9).
