There r 6 trignometric functions,namely sin a cos a tan a cosec a sec a cot a where a is the angle. Trigonometric functions didn't exist without angles.
Not sure what the question means. These are abbreviations for the three primary trigonometric functions of angles: sine, cosine and tangent.
It helps, in this type of problem, to convert all trigonometric functions to sines and cosines. As a reminder, tan(x) = sin(x) / cos(x).

To simplify such expressions, it helps to express all trigonometric functions in terms of sines and cosines. That is, convert tan, cot, sec or csc to their equivalent in terms of sin and cos.
"COS" stands for "Cosine", which is one of the 6 trigonometric functions. Similarly, "SIN" stands for Sine, and TAN stands for Tangent.

It helps, in this type of problem, to convert all trigonometric functions to sines and cosines. As a reminder, tan(x) = sin(x) / cos(x).
The solution is found by applying the definition of complementary trig functions: Cos (&Theta) = sin (90°-&Theta) cos (62°) = sin (90°-62°) Therefore the solution is sin 28°.
cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272

sin(82.2) = 0.9907 cos(82.2) = 0.1357 tan(82.2) = 7.3002
cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272
sin, cos and tan
Just like most any other set of functions, trigonometric functions are subject to differentiation. Trig functions are cool (at least sin and cos are) because as you differentiate, they cycle through until you get back where you started.
include file math.h and you get most C++ functions for trigonometry, for instance,sin(), cos(), tan(), asin(), acos(), and atan() etc.
