Find the quotient and any excluded values.
(x + 5/x^2 + 9x + 20)/(x^2-16/x-4)
1 answer:
By <span>(x + 5/x^2 + 9x + 20) you apparently meant the following: x+5 ---------------------- x^2 + 9x + 20 and by </span><span>(x^2-16/x-4) x^2-16 you apparently meant --------------- x - 4 Please use additional parentheses for clarity. Dividing, </span> x+5 (x-4)(x+4) ---------------------- * --------------- x^2 + 9x + 20 x-4 Now, x^2 + 9x + 20 factors into (x+4)(x+5), so what we have now is (x+5)(x+4) ------------------------- = 1 This is true for all x, so there are no exclusions. (x+4)(x+5)

Cos (π/2 - x) = sin x = 3/5 tan x = sin x / cos x = 3/5 / 4/5 = 3/4 csc x = 1/sin x = 1 / 3/5 = 5/3 sec x = 1/cos x = 1 / 4/5 = 5/4 cot x = 1/tan x = 1 / 3/4 = 4/3.
