Students are taught the "unit circle" and its relationship to trigonometry, but many fail to make the leap on how crucial circles are for trig functions. With static graphs and equations ...

In high school, you probably learned that trigonometric functions – like sine ... (These are only the same value in the case of a unit circle!) This is why the square does not trace a straight ...

Trigonometric functions are often used in embedded systems ... routines using the CORDIC Algorithm onInfineon's XC164CS Microcontroller with MAC unit. The implementation ofthe algorithm is examined ...

You might have already passed that silly course with a title something like "Introductory Algebra and Trigonometry ... that it's easy to show trig functions with a circle, but trig functions ...
