Legend x and y are independent variables, ;These tables are the formulae needed for side and angle functions of a right triangle In case you need it, here is the Triangle Angle Calculator, and the Right Triangle Angle And Side CalculatorStep 1) Use the Double angle formula Sin 2x = 2 Sin x Cos x Step 2) Let's rearrange it and factorize 2Sinx Cosx – sinx = 0 Sin x(2 cos x 1) = 0 So, a) Sinx =0 or b) cos2x 1 = 0 Step 3) Let's consider Sin x = 0 (Refer to the graph) We have two solutions as x = Π & x = 0

The differentiation of trigonometric functions is the mathematical process of finding the derivative of a trigonometric function, or its rate of change with respect to a variableFor example, the derivative of the sine function is written sin′(a) = cos(a), meaning that the rate of change of sin(x) at a particular angle x = a is given by the cosine of that angleTan(x y) = (tan x tan y) / (1 tan x tan y) sen(2x) = 2 sen x cos x cos(2x) = cos ^2 (x) sen ^2 (x) = 2 cos ^2 (x) 1 = 1 2 sen ^2 (x) tan(2x) = 2 tan(x) / (1Formulas in Plane Geometry;
