Excel has built-in functions for sine and cosine, the two core trigonometric functions, and for hyperbolic sine and hyperbolic cosine, their hyperbolic counterparts. It also has built-in functions for ...
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 ...
Your circuit prototype finally is complete, and now you need a signal source to test it. The function generator is a good choice. It can provide sine, square, and triangular waveforms from fractions ...
