Sine Wave(redirected from Cosine curve)
Also found in: Dictionary, Thesaurus, Medical, Encyclopedia.
Any curve plotted along an axis where the y-value moves above and below zero at a rate of y = sin(x). The Composite Index of Lagging Indicators is thought to be roughly a sine wave because interest rates and inflation, which make up the index, move in relation to each other in a way resembling the sine.
