Find the rectangular equation of the curve.

x=5tant,y=sec2t,-Ï€2<t<Ï€2

Short Answer

Expert verified

The required equation isx2=25(y-1)

Step by step solution

01

Step 1. Given Information

The given parametric equations arex=5tant,y=5sec2t

02

Step 2. Explanation

We will use the pythagorean identity, sec2t-tan2t=1to find the required equation.

Let us obtain the value of tantandsectin terms of xandyfrom the given parametric equations.

localid="1648802898629" role="math" 5tant=x⇒tant=x5y=sec2t⇒sect=±y

Substitute the values in the pythagorean theorem,

±y2-x52=1y-x252=1x2=25y-1

Thus, the obtained equation is of parabola whose focal distance is localid="1648803390459" a=254and whose vertex is at the point with coordinates 0,1
