View Full Version : Trigonometric Feeling

Sometimes I feel like the whole world is a sin (x) while I'm sin (x + 0.25).

Or something similar anyway.

Know what I mean?

It was a little bit like that this morning as well as right now.

Oh, well...

No. I can honestly say I have no idea what you mean. At all. What?

Especially since your chart indicated you are sin(x - 0.25)

Well look at the bright side, at least you're not a cos(x) and the rest being a sin(x). Although, I could see that having its benefits. But I have to say, tan(x) FTW!

As in, "I'm slightly out of sync", or as in "I get up too early but have no abilities, whether supernatural, extraordinary, spell-like, divinely granted, physical or genetic or any given combination of all the above that would indicate that I can stay awake longer than any other given average human being so as to make getting up too early beneficial rather than detrimental"?

I thought this was a thread about people who do poorly understanding trig, and I was _all ready_ to sympathize with them.

No; the original post is right. f(x-a) shifts the graph to the right by a. f(x+a) shifts the graph to the left by a.

I know what you mean, although for me it's a little bit more like the world is sin(x) and I'm 1.2sin(x+(pi/12))+.1, if that makes any sense at all. Of course, it's possible I'm just some chaotic function.

You know I don't get trig (haven't taken it). I always ask people what cosine and when do you use it. They always 'I dunno'.:smallannoyed:

I use trigonometry occasionally at work. I find the areas paving or grass or decking and sometimes I need to find the surface area of roof from plan taking into consideration the slope.

I sometimes feel like I'm 0.8*sin(x) where everyone else sin(x) as my low points aren't so low but my high points aren't so high. Like a kind of repression.

Maybe your phase inducers are offline. :smallbiggrin:

Sometimes I feel like everyone else is sin(x) and I'm x^2. Sometimes I feel like everyone else is sin(x) and I'm 3sin(x). Sometimes I feel like everyone else is sin(x) and I'm some sort of wierd fractal.

Please tell me someone ACTUALLY said that during the game?

Other than when using a graphing calculator, I could never solve (sin) (cos) and (tan) equations. I also never been given an instance where they would have been useful to figure out anything. To this day, I can only assume they somehow are usful for finding radio stations or something similar.

Back on topic,

To the OP.

Sorry to hear that. If it makes you feel any better, we could hire a statistician to help you figure out why you are out of sync. At the very least, he can tell you that 30% more of the population feels just like you do, and that 50% of his statisics are made up on the spot.

Thank you to the OP for a great graphic. I'm definately using that one in my class. Anything else similar, please PM me.

I must be a bit different to most in that I saw the pabove plot and thought "why's the x-axis in numbers and not multiples of pi. And why is the y-axis not numbered?" I'm assuming this makes me a nerd, or just someone that's docked students too many marks for not labeling axes.

I'm not certain I could get used to all the assymptotes. Maybe tan (0.25x) would be a bit easier, though.

Never did study fractals.

I'll have to see if I can make the time to change that.

To this day, I can only assume they somehow are usful for finding radio stations or something similar.

In Pre-Calc we mostly used trig to find unknown angles and distances. Things like "A 10-ft. pole is stuck in the ground at an angle. The top of the pole extends 5 ft. away from where it enters the ground. What angle does the pole make with the ground?" I've never had to do that type of problem in a practical situation, though.

In Physics class we used a lot of trig when dealing with waveforms. This includes your radio wave example.

At the very least, he can tell you that 30% more of the population feels just like you do, and that 50% of his statisics are made up on the spot.

That's how you know he's a real statistician. For non-statisticians, a full 90% of statsitics are made up on the spot. :smalltongue:

My graphing program decided to only label the tick marks at 2.5 and multiples thereof. Not sure if/how I could change that. I've never used this particular program before and really only have it because it came with the OS.

9/10 only then :smalltongue:

I'm an asymptote. No matter how close anyone gets to me, they can never touch me.

Trigonometry... is the thing in everyone's heart which causes my head to hurt when they discuss it. It's a miracle that I got a B+ this year.

Oh, don't complain. At least a basic trig class will let you understand them. As for me, I find people to be more like the Dirichlet function, while I'm sin(x+2^(1/2)). At least we as fellow trig functions will no doubt get along well. I mean, who else can understand being 1/2 for so many values of x?
