AI Thread Summary
To find x(t) from the function x(-2t+1), start by understanding the transformations involved. First, recognize that x(-2t+1) can be rewritten as x(-2(t-0.5)), indicating a scaling and shifting of the function. By deducing x(-2t) first, you can then work towards finding x(2t) and ultimately x(t). This step-by-step approach simplifies the process of extracting x(t) from the given function. The discussion highlights the importance of breaking down transformations to solve for the original function.

Hello
here is the x(-2t+1). i want to know how can find the x(t) diagram from this picture?

Physics news on Phys.org
Take t=1 for example: You know that 1=x(-2*1+1)=x(-1).
Does that help?

Hi baby_1, try taking it in baby steps :wink: One simple transformation at a time.

- See if you can deduce what x(-2t) would be. Hint x(-2t+1) = x(-2(t-0.5)).

- From there you can probably figure out x(2t).

- From there you can try to deduce what x(t) will look like.

i want to know the step to extarct x(t) from the scaled and shifted function x(-2t+1)

Thanks
 
Thank you very much uart it solved fine.(sorry for basic question :) )
 
I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
Essentially I just have this problem that I'm stuck on, on a sheet about complex numbers: Show that, for ##|r|<1,## $$1+r\cos(x)+r^2\cos(2x)+r^3\cos(3x)...=\frac{1-r\cos(x)}{1-2r\cos(x)+r^2}$$ My first thought was to express it as a geometric series, where the real part of the sum of the series would be the series you see above: $$1+re^{ix}+r^2e^{2ix}+r^3e^{3ix}...$$ The sum of this series is just: $$\frac{(re^{ix})^n-1}{re^{ix} - 1}$$ I'm having some trouble trying to figure out what to...
