What is a vertical asymptote? Vertical asymptotes are vertical lines which correspond to the zeroes of the denominator of a rational function. The graph of the rational function will never cross or even touch the vertical asymptote(s), since this would cause division by zero. MathHelp.comWhen...
For what values of t is the tangent line to the parametric curves {eq}x = t^3 - t {/eq}, {eq}\ y = t^2 - 1 {/eq} vertical?Slope of a Parametric Curve:Consider a parametric curve given by the equations {eq}\displaystyle x=f(t) {/eq} and {eq...
Vertical Line TestOn a graph, the idea of single valued means that no vertical line ever crosses more than one value.If it crosses more than once it is still a valid curve, but is not a function.Some types of functions have stricter rules, to find out more you can read Injective, ...
What is the slope of the line tangent to the polar curver=cosθ? The Slope of the Tangent Line: To compute the slope of the line tangent to the polar curver=f(θ), we'll use the formula:dydx=drdθsinθ+rcosθdrdθcosθ−rsinθ. ...
