College in Canada must suck.

Dude, if I got questions like that, I would be jumping for joy. It's cake work. College HERE (NY) is HARD.

THIS ISNT MY COLLEGE WORK,
you buncha knobs.
A friend PM'ed me this material and asked me to help, but i was too busy so i posted it here

Cobraboy is right. This is quite an easy problem if you know trig. Use the SOHCAHTOA acronym to work out what you're doing.

If you have the length of the hypotenuse, then all these calculations are easy. Remember, that if you're trying to calculate the length of the side NEXT to the angle you know (so in this case, side X is next to 44deg), use sin. Take the sin of the angle, and you get a number less than 1. Multiply this number by the length of the hypotenuse, and you will have the length of the side.

Therefore, your solution is
x = 8*sin44 = 5.75.

You can calculate the length of the other side in the same way,
y = 8*cos44 = 5.57.

Or, you can do this the other way around, using the other angle,
x = 8*cos46
y = 8*sin46

I don't know advanced math. But I wish I did.

Meh, this isn't advanced. I learned this 15 years ago, when I was 15.

(which will also be my excuse if any of it is wrong!!)

I had to take two remedial math courses in college before I could get credit for math. After that I took the minimum for my major and that was the end of it. Pre-calculus is as far as I made it.

As I get older I become more interested in physics and wish I understood math more. Now that I actually want to know it, I have very little time.

I was always more of a words type of person and not a numbers person.

Live and learn, I suppose.

I learned this when I was 12... which is also my excuse for not remembering!

Actually this is for a 15 yr old friend of mine too

Uh huh, I bet.

GT3 - my college was fairly hard, too - I learned this in sophomore high school, give or take.

you bastard guy
i was busy doing my own stuff for college, she is in grade 10 and needed to know this and i knew someone here would help me out

 

[1X83Z]

Oooh... she.

Hey guys, I actually need some Math homework help too, but I need a scanner first. So right now I'll just give you an overview of what I have to do. I basically have to draw a fish on my TI-83 Plus using a program and using any math function, lines, parabolas, cubic functions, ellipses, hyperbolas, quartic functions, circles. I have a few of the equations but when I get the fish to a scanner I'll post it here. Until then dont fret none

 

[Deathhawk]

I can show you how to do that. That is easy.

Give me a second.

Ok here you go.
#1. Set your window to trig mode.
#2. Set the window as follows:
a. xmin = 0
b. xmax same
c. y min = -4
d. y max = 4
#3. set your y= as follows.
y1 = 2cos(.75X)
y2 = -2cos(.75X)
y3 = 80000X (or some other ridicululy large number

Now if you need to define your domain and range, it is as follows

y=2cos(.75x) ; D:{ 0<= X <= 2(pie), X E R} R:{ Y E R }
y=-2cos(.75x); D:{ 0<= X <= 2(pie), X E R} R:{ Y E R }
y=80000X ; D:{X E R} R:{ -2 <= X <= 2, Y E R }

Have you got to the unit circle yet? Have fun with proofs and applications.

Here's your fish...

 

[Cobraboy]

I did this sorta work this year and in my end of year exam I got 59% - 3rd highest in the class, possibly the school. I got such a bad mark because of stupid mistakes, so I wouldnt be surprised if that is completely wrong....

 

[TAFJonathan]

Do you really need help with that?

 

[dredknot_420]

i dont even know what it is.
