Find the equation for the line tangent to the parametric curve:

How do you find the equation of a parametric curve?

Each value of t defines a point (x,y)=(f(t),g(t)) ( x , y ) = ( f ( t ) , g ( t ) ) that we can plot. The collection of points that we get by letting t be all possible values is the graph of the parametric equations and is called the parametric curve.

What is the tangent of a parabola?

A tangent is a line that touches the parabola at exactly one point.

What is the formula of parabola?

Given the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y – mx – b)^2 / (m^2 +1) = (x – h)^2 + (y – k)^2.

How do you find tangent?

In any right triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A). In a formula, it is written simply as ‘tan’. Often remembered as “SOH” – meaning Sine is Opposite over Hypotenuse. See SOH CAH TOA.
