To solve this we need to convert 3/4 into a fraction x/8 so that they have the same denominator.
To do this we can set a porportion and find a common denominator. 4 x 2 = 8 so the common denominator would be 8 and the rule would be x 2 so 4 x 2 = 8 and 3 x 2 = 6
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.
