Sin (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 The functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functionsPolynomial Identities When we have a sum (difference) of two or three numbers to power of 2 or 3 and we need to remove the brackets we use polynomial identities (short multiplication formulas) (x y) 2 = x 2 2xy y 2 (x y) 2 = x 2 2xy y 2 Example 1 If x = 10, y = 5a (10 5a) 2 = 10 2 2·10·5a (5a) 2 = 100 100a 25a 2 Using the binomial expansion of (x y) ^3, we can write (x y)^3 = 1x^3 3x^2y 3xy^2 1y^3 where the coefficients come from the 3rd row of Pascal's triangle the first row = 1 = row "0" sosubstituting for x and y, we have (50 3)^3 = 1*50^3 3 (50)^2 (3) 3 (50) (3)^2 1*3^3 = 125,000 1350 27 =
