Note that when the line is vertical the slope is undefined. What's the vertical change? A vertical shift is when the graph literally moves vertically, up or down. The movement is all based on what happens to the y-value of the graph. The y-axis of a coordinate plane is the vertical...
Consider the following: x = t^3 - 12t, \space y = t^2 - 5 (a) Find \frac{dy}{dx} \space and \space \frac{d^2y}{dx^2} (b) For which values of t is the curve concave upward? Find dy/dx and d2y/dx2, slope and concavity (if...
Where m is the slope and b the y intercept. If we know two points on the line the slope is: m = (y2 –y1) / (x2 – x1) If the line is vertical then m = (y2 – y1) / 0 = undefined! This presents a problem when writing CAD programs. Therefore the parametric equation fo...

(b) For which values of t is the curve concave? Parametric Curves: We find the first derivatives of the parametric equations of the curve. The quotient of these first derivatives gives us the slope of the tangent line....
The STRAFE also comes with swappable WASD and QERF keycaps that have a grated texture and slope inward. This is aimed at FPS and MOBA players, but I found the sloped keycaps to be awkward. Of course, the keycaps are optional. The stock keycaps also sport a matte finish that makes fo...

This is to avoid the problem of a negative serial return covariance, resulting in an undefined spread.3 The next proxy we use is a spread estimate that is generated numerically using the Gibbs sampler, a simulation procedure based on the Markov Chain Monte Carlo simulation technique. Hasbrouck ...
