Find the exact values of sin(2u), cos(2u), and tan(2u) using the double-angle formulas. cot(u) = −9, 3/2 < u < 2

sin(2u) =
cos(2u) =
tan(2u) =

answer: the answer for that is 22/3

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)

x< -17/2 hope this
