Hi I need to graph 10sin(314x) but I need all x values to be positive, effectively creating a "bunny hop" along the x axis. I know you can use y=|x| for absolute x values in linear graphs, is there an equivalent for sine waves or cosine waves for that matter?

This is in relation to half wave and full wave rectification of AC power if you are a physics person.

THANK YOU!

Half wave rectification in AC circuits is just a sine wave with the negative y values made positive.

y = 10 |sin314x| should do it . I guess it depends on how you are doing the calculations...a computer will cope.

Sure. The return of the sine function is going from +1 to -1 and the 10 is just going to scale it up to +10 to -10 applying the absolute just makes the range 0 to +1 at twice the rate.

Using full-wave rectifiers you can effectively 'convert' the negative part of an AC signal into positive. Rectifiers in essence create the equation y=|x|.

For full wave rectification,
y = |10sin(314x)|
For half-wave, leave out every other hump
(y = 0 if π(2n - 1) ≤ x ≤ 2π(2n - 1) )

what you entered became the sin fee at one million degree. that's incredibly small. The sin graph has a unfold between 0 and 360 and then it starts repeating back. i.e. sin 361 = sin one million
