Cosine and sine of an angle θ are defined to be the x and y-coordinates of the point P on the unit circle with the property that the line from O to P makes and angle θ with the positve x-axis. cos(θ) ...

I am have a slight problem with two recursive functions I wrote: Sine and Cosine. Each function depends on the other (and itself) to compute the value of Sine and Cosine for any value input. I am ...

In support of efforts to foreground functions as central objects of study in algebra, this study provides evidence of how secondary students use trigonometric functions in contextual tasks. The author ...

Abstract: Semi-supervised learning can effectively utilize limited labeled data and large amounts of unlabeled data to achieve fault diagnosis on process industries. This paper proposes a novel cosine ...
