what are you graphing? what function are you using? what class?

[JETS5128]

It's for pre-calculus. I have to graph r/theta=12

[awfullyquiet]

It's for pre-calculus. I have to graph r/theta=12

which is 12theta = r
or the radius = 12 times the degree. i think.

is that the right question for real?

[JETS5128]

That's what i did, but isn't 12theta just a diagonal line? How can you graph a diagonal line on polar paper?

[The Unseen]

It's not a diagonal line at all. r = theta is a spiral. theta*12 would probably be a pretty zany spiral.

[awfullyquiet]

it's not. it's a spiral.

you know the spiral of archamedies? function of theta = theta? (the polar equivalent to x = y (fyi))

[CashmoneyDrew]

Math sucks. You guys might as well be speaking Mandarin right now. So glad I got done with math a couple of years ago.

zing. zoom. man, i miss the days when math was actually easy.

[JETS5128]

your right, and the spiral is ****** HUGE

[JETS5128]

CAn anyone help me on how to graph it now?

[The Unseen]

I think I know what you mean by "polar equivalent," but not to confuse JETS here, r = theta is not the polar equivalent of the xy coordinate line x = y. It's sin(theta) = cos(theta).

[awfullyquiet]

I think I know what you mean by "polar equivalent," but not to confuse JETS here, r = theta is not the polar equivalent of the xy coordinate line x = y. It's sin(theta) = cos(theta).

true, but as far as the most basic function you could acquire in either coordinate system, they're 'equivalent' in concept not in actual form.

change your scale. don't go by 1's, go by 10's or better yet let each tick = 120, so for every 10* you move 1 tick.

is that confusing?

[JETS5128]

Not trying too be annoying, but time is of the essence here

when r = theta, that means the distance a point is from the center (or pole or whatever) is equal to the angle of the point. r = 12*theta means that the distance from the center equals twelve times the angle of the point. So your first point would be (0,0), your second point would be (1, 12), and so on. The problem is that the angles are in terms of pi, with each revolution around the center being 2pi. That means that the angle would be 6/pi, which you would have to estimate.

Basically, your teacher's a prick.

I'm supposed to graph each point from 0 to 360, in increments of 15 degrees. But how can i graph the point theta=15, r=180 on polar paper?

[The Unseen]

Wait, I'm assuming that you're drawing this. Is that correct?

[JETS5128]

Yes, on polar paper

[awfullyquiet]

to quote basic engineering 101.

engineers choose the coordinate plane and scale. they also do it to specification.

what does your graph paper look like? bullseyes or a regular cartesian coordinate system?

bitchin.

each one of those circles do NOT equal 1. they equal 60. in distance.

so. for every 5 degrees, you move out one concentric circle (which the scale is 1r=60? i forget). meaning at 15 degrees, you'd be moved out 180, or three concentric circles. which rtheta = 15*12 (or 180)

when you move out to 30 degrees, it'd be 30*12 or 360, which would be six concentric circles.

just make sure you put on the graph that you have changed the scale.

this. my suggestion is way wrong.

You guys are savior's, i'll rep you more once i can

[Menardo75]

I hope I never do this.

Pre-Cal? You probably will, whether it be college or HS.

[Menardo75]

Well good-bye diploma.

[CashmoneyDrew]

Well good-bye diploma.

Pre-cal/trig isn't too bad. I'm abysmal at all things math and I made it out with a B. I didn't have an easy teacher either.

[JeffSamardzijaIRISH]

Your graph should look something like this

http://education.yahoo.com/homework_help/math_help/solutionimages/miniprecalcgt/7/1/1/miniprecalcgt_7_1_1_7_60/f-565-13-1.gif

so you get r=12theta. so radius increases with the angle. graphing polar coords you use (r, theta) where r is the radius and theta is the angle. so in this case substitute 12theta for r and get (12theta, theta).

[Menardo75]

I hope your right.

[yo123]

I took trig/precalc last year and I never did this stuff. The class did suck though, then again math isn't really my thing.

[themaninblack]

I have to take precalc this summer and I'm already hating it. It's not that I'm not good at math, its just that I don't ******* care.

[CJSchneider]

This is why I am an English teacher.

[The Unseen]

I found Pre-Calc enjoyable. I'm not a "math guy," meaning that I am not planning to have a career in something math-related, but I do like math overall. To each his own, I guess.

[TitleTown088]

I hate math. Prob why I'm a history major.
When life gives you lemons, say **** it and bail.

Well maybe life gave you history lemons.

[CashmoneyDrew]

In high school I took Algebra 1 (A), Geometry (B), Algebra 2 (F), Pre-Cal/Trig (B).

As you can see, my Algebra 2 teacher was a complete *****. Made an A in summer school.

Math is awesome.

You probably know this already, but...

1. That's algebra
2. Of course that's wrong. You're dividing by zero when you divide out (a-b), which is a no-no.

i know both, i mean i am asian :D

I'm an engineering major and I think polar sucks.

AQ, write me a mathcad code for bisection to find the roots of tan(x)-3.5/x.

So many bad memories from my Maths degree... :(

Math should really be done after Geometry, your never going to use any of that other ****.

Calculus is probably more useful than geometry.

I am just gonna bump this:

Boolean Algebra, if anyone can shot me the answer with like boolean Algebra the Xs and so on, id be very thankful. i got the answer, but i have a mistake in my calculations:

There are three men A,B, C. Everyone has a different hair color, one has blond, one brown and one has black hair. They also have different beards. One has a goatee, one has a whisker and one has a moustache.

1)Person C neither has black hair nor does he have a whisker.
2) The man with blond hair is neither B nor does he have a moustache
3)in case the man with the moustache is B or C, then the man with black hair has a goatee
4) in case B has black hair, the man with brown hair doesnt have a goatee.

How do A,B,C look like?

[Malaka]

lol same here Algebra 1 B Algebra 2 1st quarter C 2nd quarter D 3rd quarter F

My algebra 2 teacher is not terrible but is very boring, and I mean just looks at the board and talks to himself for 2 hours, it also doesn't help I have skipped that class 3/4 times, well I am improving from a 33 to a 52 :D

I have not taken Geometry or Pre-Cal since I am a freshman. But man I hate math with a passion, same with Chemistry, anything with numbers = FAIL

i don't know this mathcad that you speak of... but matlab is the program we used to do this type of stuff... yea, programming blows, and numerical methods are probably the lamest thing every invented.

if i wanted to do programming i would have been a computer engineer or a software engineer. Hell, even an electrical engineer. I picked mechanical engineering because i didn't think i'd have to deal with bull **** like that.

thanks for ur help
