YOUR QUESTION:My class read the story The Hitch-hiker and our teacher has assigned us a five paragraph essay on this question: Who is the Hitch-hiker?

I don't really understand what she is asking for and there is no way I can reach my teacher.

This is due tomorrow so please help me soon!

TYPE OF QUESTION: History
YOUR QUESTION: What is the message of this source?

I'm not positive, but I think it's speaking to the serious issues David Lloyd had to balance even in the midst/aftermath of a war. Most people's distractions were minor day to day things, while someone like David Lloyd was balancing the greater picture - and doing pretty well.

There's a lot of media out there called The Hitch-hiker. My guess would be the one by Lucille Fletcher, but I'm not sure, so it makes it a little hard to help you.

But I would say: analyze what the hitchhiker said or looked like or the feelings they invoked in the narrator. What clues do these give you about the hitchhiker? Discuss those things you noticed in the story, probably one per paragraph, to determine who the hitchhiker is. Do they represent the narrator's conscience, for example? (That really is just an example.) What purpose did the hitchhiker have in the story?

TYPE OF QUESTION:
Math (Solving trigonometric equations)

YOUR QUESTION:
Solve cosx=0.184 for all solutions on the interval (0, 2pi)

I thought this seemed easy enough, but I can't seem to get the right answer?
What I did was take the inverse cosine of 0.184 which gave me 1.562, but the answer key says x=1.39 and 4.90
I'm not sure how it got that.
I can't do any of the problems because I seem to be confused on what I thought was an easy topic, help please? <3

Okay as it turns out my caluclator was just giving me the wrong answer...
But I still am confused as to how you get the second answer of 4.90?

How does the book describe him? And also think about the way he is explained!

YOUR QUESTION:So, the paper says "LaShawn wants to buy some music online. There are two plans to choose from. The first plan the a flat rate of $1.29 per download. The second plan has a membership fee of $21 and a fee of $.99 per download. let x be the number of downloads and C be the cost.

When will the cost of Plan 1 be equal to Plan 2?" I don't know how to figure this one out..

ok so you can express the two equations you've been given like this:
C = x * 1.29 ....<---- plan 1
C = 21 + x * 0.99....<---- plan 2

because they both equal C you can then set them equal to each other
x * 1.29 = 21 + x * 0.99
now you want to get the x terms all on one side
x * 1.29 - x * 0.99 = 21
now simplify! 1.29 - 0.99 = 0.3
x * 0.3 = 21
now divide by 0.3 to get x on its own
x = 21 / 0.3
x = 70

since x was the number of songs you can now put it into a sentence :) so the cost of Plan 1 will be equal to Plan 2 when you download 70 songs!

With the inverse of cosine you will get the lowest positive value of x, i.e., the value of x that belongs to the interval [ 0; π ].

If you notice in the trigonometric circle, there are two different angles with the same value of cosine: on the first and the fourth quadrant, which means x (Q1) and the respective reflection by the x-axis, -x (Q4). In this case, the value of x you'd get would be approximately 1.39.

-x would imply a negative number which doesn't belong to the interval they're giving you. Nevertheless, we know cosine is a periodic function with period 2π, which means every time you add or subtract 2π to a certain value of x, the cosine will remain the same. So all you have to do is to add a multiple of 2π until you get a value of x that belongs to [ 0; 2π ]. In this case you just have to add it once: -1.39 + 2π approximately corresponds to 4.90.

Anyway, whenever you need it, remember that the sine and cosine repeat themselves periodically until infinity. So if you need to use the inverse functions on the calculator to get the result, the general formulas are:


cos α = x ⇔ α = cos^-1 x + 2kπ V α = -cos^-1 x + 2kπ , k ∈ ℤ
sin α = x ⇔ α = sin^-1 x + 2kπ V α = π - sin^-1 x + 2kπ , k ∈ ℤ

tangent is slightly different, but the same reasoning can be applied: it has a period of π, so the general formula is;


tg α = x ⇔ α = tg^-1 x + kπ , k ∈ ℤ

Oh my gosh I read your reply and never thanked you, I'm so sorry about that!
But thank you so much for typing all this out for me, trigonometry was never really my strength so when I don't understand something pertaining to this chapter I get really flustered, so thank you very much <3
