The basic equation is of general form y = R(x) where (here) R is the Sine, Cosine or Tangent of x, and consequently the Sine and Cosine curves plot oppositely from +1 via 0 to -1 (minus 1) over 180º. The y-values of the Tangent curve goes cyclically from 0 to infinity as x goes from 0º to 90º: it looks odd at first, and you might even think you've gone wrong!
Plot in the usual way: left-hand column or top row for suitable increments of x = [angle in degrees], neighbouring columns or rows below for the corresponding ratio values. To get the best out of it, plot 0º to 360º, to give a whole Sine Wave cycle - it and the Circle to which it can be related geometrically, being perhaps the 2 most important curves in Nature!
Yes.
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.
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.

Students who have successfully completed Algebra II may take this year long elective course that extends both algebra and trigonometry topics. Emphaisis is on functions and their inverses, equations and inequalities, graph theory, matrices, sequences and series, conic sections, and logarithms. Trigonometry topics include triangular and circular definitions of the trig functions, trig identities, and solutions of trig equations. This course is designed for students who do not plan to continue with math studies in high school but needed to strengthen and extend their foundations in algebra and trigonometry. It does not meet the prerequisites for Calculus AB and BC.
