Alg2 Problem

13^13+13^20/80^-42^(16^-2\4^-1-(32^2)/(2^6-4^2))
This is an actuall problem my Math teacher gave our class.
This was the VARY FIRST problem of the new semester.
Note: All notation is VB notation.
It took me a whole 1 min to figure it out ;)
He made us show the work.
So, can you solve it? If so show ALL of your work (scann the paper if you can) I wana see the processes you all take.

Error 11: Division by zero

[Hdx]

it was made so that you couldnt just compile it -.-
That day we were in the lab, and it has a VB compiler.
So..

I would hope so, thats definately pre-algebra1 material :)

[deadly7]

Yeah, it's pre-algebra 1.  It's just long and pointless.  I solved the first half and got sick of it.

Was that an insult or something?
Sorry, I just thought you all didnt want to see alot of :
Solve: ...x^(z-sqrt(n))....
where
x = blah
z = blah
n = blah
I substituted all the vareables for the numbers.

The notes for the day were EXTREAMLY easy.
Notes 6.1
:/ meh Heres a hint, DO NOT start at the left.

It wasn't an insult, it was just a statement.  This really is pre-algebra material.  PEMDA (order of operations) is the first thing we learned in 5th grade math (pre-pre-algebra).

Eww. We did this crap in pre-calc earlier. I swear my college-prep pre-calc math class is code name for "remedial pre-algebra" at times.

HAHAHAHA!!! You did this in PRE CALCULUS?!  Rofl!  That's rediculous!  This is why I think AP/College classes are stupid.  They can't be paced at the intelligence of the class.

Incidentally, HdxBmx, your notes are wrong:

x^-1 =\= 1/x^3

x^-1 = 1/x

x^-1 =\= 1/x^3
x^-1 = 1/x

Whops, typo.
Modifyed it to ^-2 so that I can show the actuall movement.
The formula was correct, and thats the only thing I use when reading my notes.
The examples are for my techer when he reads the notes.

Anyways, ALL math classes go back to previous classes at times.

You should be doing trig identities by now. Ewww.

We're on sin(x + y) = sin(x)cos(y) + cos(x)sin(y)

Those thingies. :)

Yeah, but you shouldn't be doing order of operations in Pre-Calculus.  Additionally, not all classes recurse to their prerequisites.  In Calculus, we might spend a few minutes reviewing on of the concepts of trigonometry (like the identities when we're doing implicit differentiation), but that's it.  Just to save us the trouble of finding a reference.  We don't have a section of trig identities or anything like that.

We're on sin(x + y) = sin(x)cos(y) + cos(x)sin(y)

Those thingies. :)

All trig identities are almost intuitively obvious (if you think about it).  Have you ever looked at a sine/cosine wave function?

The core ones are:

sin^2(x) + cos^2(x) = 1
tan^2(x) + 1 = sec^2(x)
cot^2(x) + 1 = csc^2(x)

I'm bored, so If anyone feel like cretiquing (sp?) my old notes. Go ahead

I'm in to process of orginizing all my notes, and typing them out, I have horrid handwriting so some of the numbers may be off, If so, tell me please.

Anybody want to explain Law of Tangent and Law Of Cosine to me? (Basically just tell me what they are, I can figure the rest out. :D)
