3. Indicate whether each of the three reciprocal functions (cosecant, secant, and cotangent) is a periodic function. If so, state the period of each.
4. List the domain and range for the secant and cotangent functions. (Use "pi" for π.)
5. Compare the graphs of the cosecant and secant functions. How are they different? How are they similar?
Step-by-step explanation:
1. All the trigonometric values can be found using the unit circle. See attached table.
2. Graph:

3. All trig functions are periodic functions. The period of secant and cosecant is 2π. The period of cotangent is π.
4. Using the table from step 1 and the graph from step 2, secant has a domain of x ≠ pi/2, 3pi/2 and a range of x ≤ -1, x ≥ 1. Cotangent has a domain of x ≠ 0, pi, 2pi and a range of -∞ < x < ∞.
5. Graph:

Cosecant has the same graph as secant shifted π/2 to the right. So they have different domains, but the same range.
In the second version, you are given five attempts, but the target is smaller, and you estimate that your probability of
success on any given throw is 0.05. The prizes for the two versions of the game are the same, and you are willing to
assume that the outcomes of your throws are independent. Which version of the game should you choose? (Hint: In
the first version of the game, the probability that you do not get the prize is the probability that you fail on all three
attempts.)
Answer:
And the probability of loss with the first wersion is 0.729
And the probability of loss with the first wersion is 0.774
As we can see the best alternative is the first version since the probability of loss is lower than the probability of loss on version 2.
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Alternative 1
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
We can find the probability of loss like this P(X=0) and if we find this probability we got this:
And the probability of loss with the first wersion is 0.729
Alternative 2
Let Y the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
We can find the probability of loss like this P(Y=0) and if we find this probability we got this:
And the probability of loss with the first wersion is 0.774
As we can see the best alternative is the first version since the probability of loss is lower than the probability of loss on version 2.
