The tangent.
The basic functions of trigonometry are: sine cosine tangent secant cosecant cotangent
tangent, cosecants, secant, cotangent.
The principal Trigonometric function is Sine(Sin). It has a complementary function Cosine (Cos). Bases on these two functions, are further trig. functions. they are. Tangent(Tan) = Sin /Cos Cosecant(CSC) = 1/Sin Secant (SEC) = 1/Cos Cotangent(COT) = Cos/Sin The word 'Sine' comes from Latin , and means 'curve'. Initially you learn it between 0 - 90 degrees. It is a continuous 'wave', from infinity to infinity. . The Sin/Cos functions only range from -1 to 1 through '0'. The Tan function ranges from negative infinity to positive infinity, through '0'. For a triangle inscribed in a circle. At the circles centre, the radius may be '1' unit. If the radius is angles at 30 degrees from the horizontal(x) axis, then the vertical (opposite) lines perpendicular height of the triangle is exactly '1/2' ( 0.5), compared to the radius. Hence the Sin( 30 degrees) is opposite / radius(hypotenuse) = (1/2)/1 = 1/2 All the othesr trig. functional answer are based on moving the radius from horizontal to vertical. with in the described circle. This is why it produces , such 'horrible' decimal figures. Have a look in Castle's Four Figures Tables, rather than using a pocket calculator, and also graphs of the Sine/Cosine and Tangent curves.

The tangent and cotangent functions.
The trigonometric functions sine, cosine, and tangent were not invented by a single person. They have been developed and studied by various mathematicians over centuries, with contributions from ancient civilizations such as the Babylonians, Greeks, and Indians.
You can use your trigonometric functions (sine, cosine, and tangent).
The basic circular functions are sine, cosine and tangent. Then there are their reciprocals and inverses.
