5 x 1,000 = 5,000 a week or 20,000 a month.
take 1,000 divide by 5 and you get 200 a day
$400 on december 31
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.
1/2 is the greater fraction
