    (b) 2 tan x cosec x = 3

    (c) 5 sin x cos x = sin x

    (d) 2 tan^2 x = sec x tan x
    (a) Solve tan x = 3/4.

    (b) Note that the equation can be re-written as \displaystyle \frac{2}{\cos x} = 3 where \sin x \neq 0.

    (c) Solve sin x (5 cos x - 1) = 0.

    (d) Solve tan x (2 tan x - sec x) = 0.
