What it means: Thereâs blood in your pee, a condition called hematuria. That's never normal, so you should get it checked out as soon as possible,â Dr. Griebling says. Causes of bloody urine include trauma, kidney disease or cancer, inflammation or an infection in the kidneys, and more.
The most familiar AC waveform is the sine wave, which derives its name from the fact that the current or voltage varies with the sine of the elapsed time. Phase is a particular point in time on the cycle of a waveform, measured as an angle in degrees. A complete cycle is 360Â°. The waves are in phase if the waves are either 0 or 360Â° apart. The resulting amplitude (sum of the waves) is twice the original. They are out of phase if the resulting amplitude is between 0 and twice the original.
Let's take a sine wave ( f(x)= sin(x)) A cosine wave can be represented as sin( pi/2 - x ) Now let's plot both the functions in the same graph: The cosine wave is the sine wave moved 90 degrees to the left. or. The sine wave is the cosine wave moved 90 degrees to the right. We say that the phase difference between the sine and cosine waves is 90 degrees. i.e The cosine and sine waves are out of phase by 90 degrees. This is for a sine and a cosine wave but this idea can be applied to other waves as well. More Answers Below.
