Well, it’s usually odd for a single student to get something for a math teacher, so to lose the awkwardness, gather some people together. Next, find a plaque/engraving place. They’re everywhere. Purchase a plaque that you could possible engrave or encase a calculator into it or something and add a little message, name, or class of whatever year you are. This would probably run about $50, if it’s small.

For five, you should be looking at some of the larger ferret cages.

Ferret Nation cages get raving reviews from rat owners. Have a look at them here: http://www.ferret.com/ferret-cages/ferret-nation-cages/300/

Super Pet cages are also fine: http://www.ferret.com/ferret-cages/super-pet-cages/210/

Here is another brand that looks great on the same site: http://www.ferret.com/ferret-cages/marshall-mansion-cages/301/

When you find a cage you like, use this rat cage calculator tool to determine how many rats can live in the cage based on its dimensions:

Good luck and enjoy your girls 🙂

Don’t get me wrong, the more you learn the better, but some people who don’t know any better feel like you have to have a PhD in physics to be a pilot and completely ignore the bigger issues.

This is my experience as a person who has trained through their commercial pilot land. I know there are many airline pilots on YA who could give a far more detailed answer especially as the ATP written is concerned.

The only math I’d suggest putting extra emphasis on is algebra and trig. Really most of math in flying (time enroute, fuel burn etc) at the most low tech levels is done on an E6B. Takes about 15 minutes to learn the ropes and once you pass your private you can use an electronic one which is just like a calculator. Flying big iron you’ll have a flight computer to handle all that for you. Trig only really comes in handy when you’re running a ground speed check sans area nav equipment (GPS, intertial or LORAN). Even then a) 99% of all speed math in aviation can be done by either multiplying or dividing a number by 60 and b) it is much easier just to ask a controller for your ground speed readout if you’re talking to ATC. There are other advanced formulas requiring trig or the like, but they only really qualify as cool to know, but nothing you’d ever use for the most part. As long as you have an average understanding of math, the formulas will be taught (hence the it would be good to be decent at algebra) such as weight and balance shift. As an example, drop the last zero in your groundspeed to get how far you’ll fly in 6 minutes. I don’t need a PhD to drop a zero. Fuel burn is X pounds / gallons per hour and at my speed I’ll need to fly for Y hours. I have Z pounds and X times Y is less than Z and i stil have the FAA or company required reserve fuel left over, yup I’ll get there. That is all pretty basic math.

It would be nice to know some physics, but like everything else, if you are decent at science it will be taught to you and you’ll be able to put 2 and 2 together. Sure when you learn about P factor early on it might be cool to know the force applied given RPM and prop size and know the rudder effectiveness and the exact deflection needed, but really, just keep your foot on the rudder and keep the pointy end aimed down the runway.

If it is offered focus on weather, fluid dynamics, electronics, law and auto shop. Not saying to skimp on the math or science, they are important. Don’t take the dummy math class, but don’t take AP calc at the expense of a weather class. You’re far more likely to get killed not knowing about weather or mechanics than by not knowing the lift drag ratio. A micro burst is going to ruin your day / life if you don’t know what conditions they form in. Likewise while no HS auto shop won’t teach you how a jet engine works, all engines suck in air, suck in fuel, compress the two, blow it up and spit it out. The other three, well, air is essentially a fluid and the fuel is a fluid. Also you’ll have to know a decent bit about avionics etc. Lastly, law seems odd, but if you get around to reading the FAR’s (and you will know them all too well) it’d be nice to know how to read lawyer speak.

Lastly, I’d strongly advise against going to a university that only offers aviation degrees as has been suggested. While the person that suggested that is very young and most certianly far more mature for their age than many, I ask you to consider this. I’ve never seen an airline that specified a math or science related degree. Most commercial pilots I know have degrees in liberal arts (english, poly sci and the like). They didn’t have any trouble getting hired by major airlines. On the flip side, if (and most pilots do) you get fulroughed, how are you going to support yourself? Your flight hours and degree in aviation are virtually worthless on the general job market. I’d look in to getting a degree in something other than aviation as a fall back. All the airlines want is a 4 year degree, doesn’t matter in what.

Again, I’m not bashing math or science, I’m just saying there are other subjects that would be more relevant. Best of luck to you in the future.

The shortcut I use is to plug the function into my graphing calculator. I always keep a y=0 in y5 or y6. Then just use the intersect feature, on the ti 83/83 its under 2nd/trace. You can then find all the zeros easily.
If you have something like x=-3/4 at one of the zeros, you would have
(x+3/4)=(4x+3)
if you know the decimal approximations for a few odd things like pi/2 or rt(3)/2 you can even spot the trig function zeros

Uh I tried and it’s -6. If you have a scientific calculator, put brackets around -2 like this:

(-2) X 3

You should be able to get -6.

All the best; hope I helped!
