Cot (45 o) = Cos(45) / Sin(45) Note the inversion of Cos and Sin. Cos(45) = sqrt(2) / 2 Sin(45) = sqrt(2) /2 Applying division of fractions. Cot(45) = Cos(45)/Sin(45) = [sqrt(2)/2] / [sqrt(2)/2] => sqrt(2)/2 X 2/Sqrt(2) Note the change of sign and the inversion of terms. Cancel down by '2' sqrt(2)/1 X 1 / sqrt(2) Cancel down again by 'sqrt(2)' . 1/1 x 1/1 = 1/1 = 1 Hence Cot (45 o) = 1
No whole numbers multiply to equal 13 but 2 x 6.5 can equals 13 * * * * * Not quite true: 1 x 13 = 13
