Trigonometry
With trigonometry we can find the height of a building or the width of a river without actually climbing or crossing. Certain basic definitions are necessary to further develop this subject. The ratios of two sides of a triangle are taken. There are six possible combinations. Each ratio i..
Trigonometry Summary
Summary - sine of an angle = cosine of its complement. If sin A = cos B, then A + B = 90 o . Trigonometric ratios of standard angles (i) sin 0 o = 0, cos 0 o = 1, tan 0 o = 0 (i..

Sum Formula
For any two angles A and B, we have 1. Sin(A+B) = SinA CosB + CosA SinB. 1. Cos(A+B) = CosA CosB + SinA SinB. 1. Tan(A+B) = (TanA + TanB) / (1 - TanA TanB). 1. Cot(A+B) = (CotB CotA - 1) / (CotB + CotA..

Graph of y = tanx
the part of the curve from p to 2 p has the same form on the part from 1 to p . This implies that the fact tan x = tan ( p + x). The whole curve consists of an endless number of branches having the same form as the branch corresponding to the values of x from..
