You’ll be able to graph sine and cosine graphs like y=cos(x) or y=sine(x) on a graphing calculator — even simultaneously, for some. Both the sine and cosine functions appear as waves that repeat.

Apart from displaying graphs of plotted equations, one of the major innovations of the graphing calculator was the ability to compute the sine, cosine and tangent trigonometric functions.

Calculators have evolved over centuries from large computing machines into today’s highly functional, pocket-sized devices capable of performing complex computations, graphing multiple lines at ...

Some functions have implementations in both MATLAB and C. The standard math C library can be used to implement functions such as divide, sqrt, cos, sin, etc. in C when dealing with real scalar data.

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, it's ...
