1.Solve each of the following equations for 0< x < 360
(a) 4 sin x = 3 cos x

(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) 4 sin x = 3 cos x

(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.
