Parametric Curves - Calculating Area enclosed by a parametric curve. In this video, I show how to set up the integral to find the area between a parametric curve and the line y = 2.5.

  • excuse Patrick but are you using the textbook "Essential Calculus: Early Transcendentals" by James Stewart?

  • @tokyo200 no, but one of the books i have around is by stewart

  • i has a question, does x = T or theta for any type of parametric equation? if so, why?

  • @FMAZON3 not on amazon, saves so much

  • @tokyo200 expensive book

  • Wouldn't at t=0 the curve be undefined?

  • AAAAaaaaaaaahhhhhhhhhhhhhhhhhh­hh dx = (1 + t^-2)dt

    Ok, I'm over it.

  • @nanohark thanks for the update..i thought we have to integrate from x=-1.5 to x=1.5 for some weird reason..

  • i know that im late but why t is from 1/2 to 3/2?isnt ir from 1/2 to 2?

  • why in the first formula of integration you write g(t) x f'(t) but in your work, you use 2.5 - y??

  • how do you decide which is g(t) and f(t) ? or is traditionally just f=x, g=y? i also wish you made physics videos :(
