The trigonometric ratios sine, cosine and tangent are used to calculate angles and sides in right angled triangles. We are now going to extend trigonometry beyond right angled triangles and use it ...

Just change the function and the initial value and compute away! Circle, Ellipses and Lissajous Parametric Curves Applet 10.1 Some of the most basic parametric curves. Here we see that circles, ...

which is given by \(k\) (since maximum value of sine/cosine is 1) its minimum value, which is given by \(- k\) (since minimum value of sine/cosine is -1) the roots of \(a\cos x + b\sin x = 0 ...
