Introduction to Trignometry

Topic:Trigonometry help

Trigonometry
is a branch of mathematics that deals with triangles, particularly those plane triangles in which one angle has 90 degrees right triangles. Trigonometry deals with relationships between the sides and the angles of triangles and with the trigonometric functions, which describe those relationships. Trigonometry has applications in both pure mathematics and in applied mathematics, where it is essential in many branches of science and technology. It is usually taught in secondary schools either as a separate course or as part of a Precalculus help
course. with the help of its Trigonometry formulas Trigonometry is informally called "trig".


Solve the equation given below:

(risin(x)cos(y)2 + (rsin(x)sin(y) 2) + (rcos(x) )2 = r)2
