What do i have to look up to learn how to do this kind of trig. I went through kahn academy for trig but this stuff never came u

mariarad [96]

Answer:

(e) √(x² -1)

Step-by-step explanation:

You can look up the Pythagorean theorem, and SOH CAH TOA.

<h3>Pythagorean theorem</h3>

This tells you the relations between the sides of a right triangle. For the purpose of finding tan(θ), you need to know the length of the side that is not marked on the diagram. It is found using the Pythagorean theorem.

The sum of squares of the legs is equal to the square of the hypotenuse. If we call the unknown leg "o", then ...

1² +o² = x² . . . . . the Pythagorean relation

o² = x² -1 . . . . . . subtract 1

o = √(x² -1) . . . . take the square root

This mnemonic reminds you of the relationship between trig functions and side lengths of a right triangle.

Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent

This tells you that tan(θ) is the ratio of the side opposite θ to the side adjacent:

tan(θ) = o/1 = o

From the previous section, o = √(x²-1), so ...

tan(θ) = √(x² -1) . . . . . . . matches choice (e)

_____

<em>Additional comment</em>

Another way to think about this is in terms of the trig identities you have learned:

sec(θ) = 1/cos(θ) = 1/(1/x) = x

sec²(θ) = tan²(θ) +1 ⇒ tan(θ) = √(sec²(θ) -1) = √(x² -1)

Consider an unreliable communication channel that can successfully send a message with probability 1/2, or otherwise, the messag

Anon25 [30]

Answer:

6 times we need to transmit the message over this unreliable channel so that with probability 63/64.

Step-by-step explanation:

Consider the provided information.

Let x is the number of times massage received.

It is given that the probability of successfully is 1/2.

Thus p = 1/2 and q = 1/2

We want the number of times do we need to transmit the message over this unreliable channel so that with probability 63/64 the message is received at least once.

According to the binomial distribution:

$P(X=x)=\frac{n!}{r!(n-r)!}p^rq^{n-r}$
