Question

3. Robbie the Robot is on a weather satellite orbiting Earth about 3600 km above the surface. The Earth’s radius is about 6400 km. He has had a malfunction in his output device, and the satellite is traveling without communication. His last report was only in terms of trigonometric values and was only partially received. It said, sin Θ < 0….. and then he was lost again.

Part 1: Create a set of coordinates that would be reasonable for Robbie’s position in space and satisfy his last, partial report. Using complete sentences, describe Robbie’s location and your reasoning.

Answer 1

Part 2: What are the values of the sin Θ, cos Θ, and tan Θ using your coordinate point?

Answer 2

I'll medal and fan!

Answer 3

Look for the Sin, Cos, and Tan of your chosen points.

Answer 4

I on Part B

Answer 5

i would change your coordinate points. ;-;

Answer 6

Ummm.... I don't think the unit circle works like that... It doesn't show the tan, sin and cos of any point....

Answer 7

Or it does, and I'm an idjit. Which is quite possible XDXD

Answer 8

Answer 9

@radar

Answer 10

It does xD

Answer 11

In that case, how the heck do I do that?

Answer 12

Sin is the Y and Cos is the X. Just look at the coordinates. You butt.

Answer 13

*facepalm*

Answer 14

xD poor you.

Answer 15

So, If I chose the coordinates, say, (-sqrt2/2, -sqrt2/2), the sin and cos would be -sqrt2/2? but in number form?

Answer 16

"number form"

Answer 17

Oh jeez

Answer 18

Noo, that is the cos. xD

Answer 19

I don't divide it out into a decimal?

Answer 20

WEIRD

Answer 21

Nopee, xD

Answer 22

ughhhhh

Answer 23

You'll love the unit circle once you get to Pre-calc. YAH. -sarcasm.

Answer 24

I figured.

Answer 25

So, in about 7 days, I'll love the unit circle?

Answer 26

EWWW

Answer 27

Then how do I get tan?

Answer 28

I know its sin over cos or whatever, but how do I do that without decimals?

Answer 29

Ill show yuh a chart c:

Answer 30

Because multiplying fractions would end with a radical in the denominator

Answer 31

OH DUH

Answer 32

1

Answer 33

Oh course its 1.

Answer 34

Duh.

Answer 35

*facepalm 12 times in a row*
