Tangent parametric curve
WebDec 28, 2024 · The normal line is horizontal (and hence, the tangent line is vertical) when sint = 0; that is, when t = 0, π, 2π, corresponding to the points ( − 1, 0) and (0, 1) on the … WebTo identify the tangent line to a parametric curve at a point, we must be able to calculate the slope of the curve at that point. If we can do this, writing the equation of the line is straightforward - we determine the coordinates of the curve at the desired point, and use the calculated slope to write the equation of the tangent line in point-slope form.

Let’s take a quick look at an example of this. The final topic that we need to discuss in this section really isn’t related to tangent lines but does fit in nicely with the derivation of the derivative that we needed to get the slope of the tangent line. Before moving into the new topic let’s first remind ourselves of the formula for … See more Notice as well that this will be a function of tt and not xx. As an aside, notice that we could also get the following formula with a similar derivation if we needed to, Why would we want to … See more Vertical tangents will occur where the derivative is not defined and so we’ll get vertical tangents at values of ttfor which we have, See more It is important to note that, Let’s work a quick example.
