Stationary point of a function is a point where the derivative of a function is equal to zero and can be a minimum, maximum, or a point of inflection
I have a cam contour that I generated using Solidworks that I exported as a series of points and fit a spline to using the spline and ppval commands. I need to analyse this cam mathematically, and to do so I need to find the gradient at many points on it, hence needing the e...
A smooth inclined plane has a gradient of 1 in 5. A body having a mass of 60 kg rests on the plane. Draw the force diagram to a scale and, from the diagram, determine the effort required to pull the body at a uniform speed up the plane if the effort makes ...
Therefore, the equation would be y = -½ + 3. The Gradient of a Curve In addition a straight line you may be asked to find the gradient of a curve. In order to calculate it, you could draw a tangent line to the curve— a line which touches the curve at one point. You then ...
The unit step response is a standard tool for experimental identification; its shape is equivalent to a solution of an appropriate governing equation. In this study, we investigate two variants of nonlinear first-order governing equation,{y'=k(1-y^\beta )/\beta }, and mainly its rescaled ve...
