They do not. They are not animate nor sentient and so they are incapable of communicating.

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.
All six trigonometric functions can take the value 1.
The range of the circular trig functions sin and cos is is [-1,1], but even in the case of circular functions the range of the tangent function is all real numbers. This is of course true of tangent even if we do not limit it to circular functions. So your question, I assume, is asking about all trig functions. If so the range is all real numbers.
cosine = adjacent/hypotenuse. It can be used as other trig functions can.
Yes.
The only trig functions i can think of with horizontal assymptotes are the inverse trig functions. and they go assymptotic for everytime the non-inverse function is equal to zero.
Trigonometry functions are used to work out the various properties of triangles.
Cosine and secant are even trig functions.
The first recorded functions had something to do with the chords of a circle.
They do not. They are not animate nor sentient and so they are incapable of communicating.

They both are trig functions, obviously. And they both represent a ratio that is the opposite side of a right triangle from the angle of interest, divided by one of the other sides.
Texas Instruments is the most well-known and popular brand of calculators, and the TI-83 and TI-84 both offer trig functions. They can be purchased at the Texas Instruments store or through other retailers like Best Buy.
