WebEjemplo: PROPIEDAD Calcule tan 8º 1.- Siendo "a" y "b" números tan8º tan(45º 37º ) reales, x variable real, se cumple: tan 45º tan 37º a Sen x b Cos x a b Sen x 2 2 1 tan 45º tan 37º 3 1 Donde: 1 4 1 4 b a 3 7 7 Sen ; Cos 1 1.WebStep 1: Compare the tan (a - b) expression with the given expression to identify the angles 'a' and 'b'. Here, a = 60º and b = 45º. Step 2: We know, tan (a - b) = (tan a - tan b)/ (1 + tan a·tan b) ⇒ tan (60º - 45º) = (tan 60º - tan 45º)/ (1 + tan 60º·tan 45º) since, tan 60º = √3, tan 45º = 1one cup of black eyed peas
