The figures indicate that the higher the orbit of a satellite, the more of the earth the satellite can "see." Let θ, s, and h be as in the figure, and assume the earth is a sphere of radius 3960 miles. (a) Express the angle θ as a function of h. (Remember to enter inverse trigonometric functions such as sin–1(x) as either asin(x) or arcsin(x).) θ (h) = (b) Express the distance s as a function of θ. (Remember to enter inverse trigonometric functions such as sin–1(x) as either asin(x) or arcsin(x).) s (θ) =

The radius of the earth is given, 3960 mi.

r -->radius of earth.

Why did you square root the denominator?
anonymous
  • anonymous
Again typo mistake :p The square root is not present
anonymous

Ah, okay. That's actually what I got too, when I tried figuring it out now. Do you think you can help me with Part B?
anonymous
  • anonymous
ok \[s = r \theta = r \cos^{-1} ({r \over r+h}) \]
anonymous
  • anonymous
got it ??
anonymous
  • anonymous
That's for s as function of theta?
anonymous
  • anonymous
\[s = r \theta\]
anonymous
  • anonymous
Got this or I need to explain
anonymous
  • anonymous
Can you explain a little bit? I'm a little confused. Is that for part b?
anonymous
  • anonymous
See I am little confused myself about s. I am assuming that they are taking s as arc length of a circle.
anonymous
  • anonymous
That's what I'm assuming too. But it's really confusing. I agree.
anonymous
  • anonymous
Do you want me to show you how to get s = r (theta) or continue to part C??
anonymous
  • anonymous
Can you show me how s=r(theta), please? Thank you so much.
anonymous
  • anonymous
See we know that circumference of circle = 2(pi)(r) If for 2(pi) angle ---> Arc length = 2(pi)(r) Then for (theta) angle --> Arc length = 2(pi) (r) / 2(pi) * (theta) Therefore Arc length = r * Theta

Oh, okay. I don't know why I couldn't get it in the first place. I was just overthinking it. Thanks! SO MUCH. Can we move on to Part C?
anonymous
  • anonymous
Part C is already done by me. Go above in this thread and check.
anonymous
  • anonymous
Oh! Got it. Got it.
anonymous
  • anonymous
Do you want me to do part d and part e or you will try by yourself??
anonymous
  • anonymous
I'll try by myself first. But can I check with you later to see if i'm correct?
anonymous
  • anonymous
Let me give you a hint because it is 4 am here and I am going to sleep now Part d) Use s= function of h In this case , h is given. Find s Part e) s= function of h. In this case , s is given. Find h

Hey, when you get a chance, I computed for the answers. I got d) about 50,462.093 miles; and e) about 0.23 of a mile.

I still do not fully understand what the answers are after reading it over and over? Starting with A what exactly is the answer?
