WebApr 17, 2015 · Since tan x is an odd function, it can be represented as tan x = a x + b x 3 + c x 5 + ⋯. Since sin x = cos x tan x, one has x − x 3 3! + x 5 5! + ⋯ = ( 1 − x 2 2! + x 4 4! + ⋯) ( a x + b x 3 + c x 5 + ⋯). Comparing the coefficients gives you 1 = a − 1 3! = b − a 2! 1 5! = c − b 2! + a 4!. Share Cite Follow answered Apr 17, 2015 at 12:30 mathlove

WebSin (θ), Tan (θ), and 1 are the heights to the line starting from the x -axis, while Cos (θ), 1, and Cot (θ) are lengths along the x -axis starting from the origin. If the acute angle θ is given, then any right triangles that have an angle of θ are similar to each other. This means that the ratio of any two side lengths depends only on θ.

WebNote that the graph of tan has asymptotes (lines which the graph gets close to, but never crosses). These are the red lines (they aren't actually part of the graph). Also notice that the graphs of sin, cos and tan are periodic. This means that they repeat themselves. Therefore sin(ø) = sin(360 + ø), for example. Notice also the symmetry of ...
