The method of "cone iteration"; is used to obtain exact bounds for the solutions of a class of nonlinear operator equations. The general theory is applied to the problem of finding radially symmetric solutions of the plasma problem in the unit circle. Existence and uniqueness results are obtaine...
A trigonometric table can be used to obtain the values of the sine, cosine, and tangent functions for the standard angles from 0 to 2π (values along the unit circle). For example, at π4 or 45 degrees, sin and cos have the value of 22....
It can be shown that the trigonometric functions of an angle {eq}\theta {/eq} in standard position can be obtained from the coordinates of the point of intersection of the terminal side of {eq}\theta {/eq} and the unit circle. If a general point on the terminal side is ...
