Answer:
b
Step-by-step explanation:
Using the trigonometric identities
cot x = and tan x =
thus
+ tanΘ × cosΘ
= +
× cosΘ
= cosΘ × + sinΘ
= sinΘ + sinΘ
= 2sinΘ → b

Answer:
The solution is .
Step-by-step explanation:
Given:
The inequality given is:
In order to simplify for 'x', we first isolate 'x' on one side.
Adding -4 on both sides, we get:
Now, is an absolute value function which is defined as:
Therefore, the given inequality can be rewritten as:
and
Therefore, the solution is .
