In summary, the conversation discusses finding a linear graph for the equation T=2pie(√L/√g). The suggested linear graph is L/T^2, and the slope is determined to be d(T^{2})/dL = 4π^{2}/g. The misconception about slope being y/x is clarified.

Homework Statement



I am suppose to find a linear graph for the equation T=2pie(√L/√g)

Homework Equations





The Attempt at a Solution



The best linear graph I could think of was L/T^2.

Am I doing it right? Thanks.

Yes.

T[itex]^{2}[/itex] on y-axis and L on x-axis.

Thank you very much. This has been like a huge thorn in my finger all day!
 
  • #4
I thought the slope was always y/x, so why isn't the slope of the graph T^2/L?
 
  • #5
Slope is NOT y/x but slope = [itex]\Delta[/itex]y/([itex]\Delta[/itex]x)
or more exactly slope = dy/(dx).

T = 2∏√(L/g)

therefore T[itex]^{2}[/itex] = 4π[itex]^{2}[/itex]L/g

so d(T[itex]^{2}[/itex])/dL = 4π[itex]^{2}[/itex]/g = slope

oh that makes much more sense. thank you.
 

FAQ: Finding Linear Graph for Pendulum Dilemma Equation

What is the equation for the pendulum dilemma?

The equation for the pendulum dilemma is a second-order linear differential equation, which can be written as d2x/dt2 + (g/L)*sin(x) = 0, where x is the angle of the pendulum, t is time, g is the acceleration due to gravity, and L is the length of the pendulum.

How do you find the linear graph for the pendulum dilemma equation?

To find the linear graph for the pendulum dilemma equation, you can use a mathematical method called linearization. This involves using small angle approximations to simplify the equation and then plotting the resulting linear equation on a graph.

What do the variables represent in the pendulum dilemma equation?

In the pendulum dilemma equation, x represents the angle of the pendulum, t represents time, g represents the acceleration due to gravity, and L represents the length of the pendulum. These variables are all important factors that affect the behavior of the pendulum.

Are there any real-world applications of the pendulum dilemma equation?

Yes, there are many real-world applications of the pendulum dilemma equation. It is commonly used in the study of pendulum clocks, as well as in engineering and physics to understand the behavior of pendulum systems. It is also used in seismology to model the movement of tectonic plates.

How does the length of the pendulum affect the linear graph?

The length of the pendulum directly affects the period of the pendulum's oscillations. As the length increases, the period also increases, resulting in a longer time for each swing. This can be seen in the linear graph, where a longer pendulum will have a flatter slope compared to a shorter pendulum with a steeper slope.
