Measuring apparatus of the derivative of a curveDEBROCK MARCEL-LOUIS
I defined the derivative d as a function. Alternatively, you can of course use x = [1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 6.0]; d = 1 - sin(x)./(2*sqrt(x)) - sqrt(x).*cos(x); plot(x,d) would this code also work?
In this paper we describe two natural ways to express the flrst derivative of a rational B-spline curve in terms of its con- trol points and weights. These expressions generalise the established ones for non-rational curves and ofier numerically stable methods for computing the derivative. Some...

By calculating the derivative of a curve at many points a new function can be obtained. By finding the equation that will fit the points, the derivative of f(x) = sin(x) and g(x) = cos(x) can be discovered. Exploration Steps 1 through 10 are details for the students to set up ...
The middle curve represents the first “derivative” and the bottom curve the second “derivative” of the absorbance bands. We have been putting the term “derivative” in quotes because they are, in fact, not true derivatives. The mathematical definition of a derivative includes the step of ...
The Slope of a Curve as a Derivative Putting this together, we can write the slope of the tangent atPas: dydx=limh→0f(x+h)−f(x)h\displaystyle\frac{{\left.{d}{y}\right.}}{{\left.{d}{x}\right.}}=\lim_{{{h}\to{0}}}\frac{{ f{{\left({x}+{h}\right)}}- f...
aIf the original curve has corner points, where the derivative is not defined, the problem of determining the intersection of propagating lines arises (see Fig. 1a,the ambiguity at the singular point produces two normals). In case of expansion of the corner point, the insertion of an addition...
