I have a ton of questions... Please help!

08 Region

45. Find the angle of rotation, [unparseable or potentially dangerous latex formula], where [unparseable or potentially dangerous latex formula], such that the conic [unparseable or potentially dangerous latex formula] contains no [unparseable or potentially dangerous latex formula] term on its equation.

First of all what is a degenerate conic? Any properties?

How do you find parallel or perpendicular vectors?

What is a right hand / left hand derivative?

They don't ask any of those conic section angle questions anymore.

Vectors are kind of like rays right, so I'm thinking if you divide the y component by the x component, and for two vectors that quotient is the same, then the vectors are parallel. If the two quotients are opposite reciprocals, then the two vectors are perpendicular.

Left hand and right hand derivatives are just like left hand and right hand limits.

You know the definition of a derivative is just a limit. A left hand derivative is just that limit approaching from the left.

So there is NO right hand derivative for [unparseable or potentially dangerous latex formula] at [unparseable or potentially dangerous latex formula] right?

Did they stop this conic angle only recently? This is cuz I saw one on a 2009 test...

Also, a question:

Captain Hool left Pan island in search of treasure. He sailed 120 leagues due west to Wendy shores. He found no treasure, so he sailed 100 leagues on a bearing of 150 degrees to Smee HArbor. Again, he found no treasure so he sailed back to Pan island. How many leagues did he sail on his voyage?

Just add the vectors.

120 leagues at -180 degrees=[unparseable or potentially dangerous latex formula]

100 leagues at 100 degrees=[unparseable or potentially dangerous latex formula]

[unparseable or potentially dangerous latex formula]

Magnitude of [unparseable or potentially dangerous latex formula]

The Voyage was a total distance of:
|V| + |R| + |W| = 120+100+[unparseable or potentially dangerous latex formula] which is approximately equal to 331.355 LEAGUES

Thanks :P
But darksaber is right with that 331.

But why the 60 degrees darksaber?

Oh my bad. It looks like I was trying to answer the question at the same time as Darksaber was. Anyways, here are two different methods I guess.

Cool. Like it! Mr Gonzalez's method comes to mind again!
