That curve above is a special function. It's called the tangent function. If you put an angle into this function, it gives you the ratio of y to x. You could write this tangent function as: ...

How to Use Trig Functions in Excel. Excel has built-in functions for sine and cosine, the two core trigonometric functions, and for hyperbolic sine and hyperbolic cosine, their hyperbolic ...

Trigonometric functions are often used in embedded systems. Motor drivecontrol applications such as the Park Transform, Clarke Transform, andPWMgeneration use trigonometric functions extensively.

The inherent symmetry of the trigonometric functions along with their relationships to polynomial sequences—such as those involving Bernoulli numbers and higher-order tangent constants—has ...
