What are the remaining trig functions? and how do i solve for them? pls help
erastovalidia [21]

You're told that tan(<em>θ</em>) is positive, but

tan(<em>θ</em>) = sin(<em>θ</em>)/cos(<em>θ</em>)

and you're also told that sec(<em>θ</em>) = 1/cos(<em>θ</em>) = -3. So if cos(<em>θ</em>) is negative, sin(<em>θ</em>) must also be negative. In turn, both sec(<em>θ</em>) = 1/cos(<em>θ</em>) and csc(<em>θ</em>) = 1/sin(<em>θ</em>) are also negative.

Now, recall the Pythagorean identity,

cos²(<em>θ</em>) + sin²(<em>θ</em>) = 1

Multiply through both sides by 1/cos²(<em>θ</em>) to get an alternate form of the identity,

1 + tan²(<em>θ</em>) = sec²(<em>θ</em>)

Solve for tan(<em>θ</em>) (which we know is positive):

tan(<em>θ</em>) = √(sec²(<em>θ</em>) - 1) = 2√2

Right away, we get

cot(<em>θ</em>) = 1/tan²(<em>θ</em>) = 1/(2√2) = √2/4

Since sec(<em>θ</em>) = -3, it follows that cos(<em>θ</em>) = -1/3.

Then

tan(<em>θ</em>) = sin(<em>θ</em>)/cos(<em>θ</em>)   ==>   sin(<em>θ</em>) = 2√2 × (-1/3) = -2√2/3

and so

csc(<em>θ</em>) = 1/sin(<em>θ</em>) = -3/(2√2)

Which of the following illustrates the truth value of the given conditional statement? If 3 • 2 = 5, then 6 &lt; 0. F F → T T T
nydimaria [60]

Answer:

Option 1. F F → T is the answer.

Step-by-step explanation:

In this question the given conditional statements are

3×2 = 5 then 6 < 0

We have to find the truth value of these conditional statements.

Since multiplication of 3×2 = 6 therefore the truth value of this statement is False.

For the statement 6<0 truth value is false because 6 is always greater than 0.

Now we know in two statements P → Q, if they follow the Implication rule then truth value is False only when P is true and Q is false otherwise in every condition the truth value is True.

Therefore F F → T illustrates the statements of the question.
