Examples
“The reason that the sinusoid is optional is that sometimes without the sinusoid, the estimated lines end up with a wavy component.”
“The complex representation of a sinusoid is a*exp(j*2*pi*f*t) = a*exp(j*omega*t), and the frequency itself is f (in Hz) or omega (rad/s), which is real by definition (f=c/lambda, both of which are real numbers).”
“The "sinusoid" form in the autocorrelation is quite common in CRU data many other gridcells are stronger and suggests to me that the normalization has not been performed very accurately.”
“By randomizing the sinusoid at the bottom, I was able to achieve the effect of a curtain hanging in long folds.”
“To create the randomized sinusoid, I took the sum of sinusoids of random frequencies.”
“This wall changes smoothly from one random sinusoid at the bottom to a different one at the top.”
“I used a combination of horizontal and vertical sinusoids to govern the displacements, and modified my previous code to make this Manipulate, with which I could experiment with the sinusoid frequencies.”
“I wrote this function that uses a sinusoid to produce a gently undulating, rounded star with n points:”
“Huge rod is what all girls dream about! musk banshee sinusoid”
“Adding a sinusoid will help remove that wavy component.”
