How Does the Function Transform from \( x = e^{2t} \) to \( x = e^{-2t} \)?

In summary, a parametric graph is a type of graph that uses two separate equations to determine the coordinates of a point, as opposed to a Cartesian graph which uses a single equation. It is commonly used in physics, engineering, and computer graphics to model motion and create animations. To plot a parametric graph, one must substitute different values of the third variable into the equations. The advantages of using a parametric graph include its ability to represent complex relationships and its flexibility in plotting curves.

x=e^(2t)

y=t+1

t= ( lnx ) / 2

y= ( lnx ) / 2 + 1

or

blah

or

y= +- ( ( lnx ) / 2 + 1 ) ?

Why did you add +- ?
 
  • #3
what i meant was for t<0 how to represent the graph in terms of y and x
 
  • #4
x=e^(-2t)
y=t+1

-2t=lnx
y=1-lnx/2
i suppose

Is this the same question? How did "[itex]x= e^{2t}[/itex]" become [itex]x= e^{-2t}[/itex]?

-2t=lnx
y=1-lnx/2
i suppose
Assuming you really did mean [itex]x= e^{-2t}[/itex], yes, that is correct.
 

1. What is a parametric graph?

A parametric graph is a type of graph in which the coordinates of a point are expressed as functions of a third variable, typically time. This means that both the x and y coordinates of a point are determined by a separate equation.

2. How is a parametric graph different from a Cartesian graph?

Unlike a Cartesian graph, which uses a single equation to represent the relationship between x and y coordinates, a parametric graph uses two separate equations to determine the coordinates of a point.

3. What are some real-world applications of parametric graphs?

Parametric graphs are commonly used in physics and engineering to model and analyze the motion of objects, such as projectiles or vehicles. They can also be used in computer graphics to create animations and special effects.

4. How do you plot a parametric graph?

To plot a parametric graph, you will need to plot points by substituting different values of the third variable (usually time) into the two equations that determine the x and y coordinates of each point. These points can then be connected to create a smooth curve.

5. What are the advantages of using a parametric graph?

Parametric graphs can be useful for representing complex relationships between two variables, as well as for analyzing motion and change over time. They also allow for more flexibility in plotting curves compared to Cartesian graphs.
