LOL  I thought maybe they had drawn it wrong or something. I have no idea what it is. :gikkle:

Hehe, it's the tangent function. :lol: The equation looks like this: tan(θ)= (y/x). That's why the person has a 'tan' line. :gikkle:

I knew the word "tangent" so got that much of the joke.  As far as the equation or whatever they drew on his arm, I have no clue if it's right or not.  I just knew you'd appreciate it. :)

Ah. :) Well, it's correct within the domain: -(π/2) < x < (π/2). Although, the function does continue beyond the asymptotes, as shown below:

I bow to your superior math ability.  :worship::hug: (and no... I do not bow to you in LPW ;) )

A lot of fun is had by man

in graphing f(x) is tan.

Cartesian, polar, using e,

or even parametrically,

the periodic tangent rules,

that's why it's taught in all our schools.

Have I suffered from brain damage at some point in my life ?  I used to know a lot of this stuff, now it's all gibberish to me ...

:facepalm:

It's hideous. The axes aren't perpendicular or geodesics...

 

My favourite formula is Euler's Identity. wpid-euler.jpg?w=625

For something drawn on an arm, I think it's fairly accurate. :)

Even so, nothing excuses those arrows on the ends of the curve. Tan lines don't come with arrows...

At the end of the day, that image is merely a joke, so I'm not going to be nit-picky with any flaws in the graph.

Wow y'all take math seriously. I'll stick with my basic quadratic equation and rise over run. And pi.  Mmm pi now I'm hungry😝

Maths is wonderful. You can do so much with it, even using something as simple as algebra...

 

Let x = y

Multiple both sides by x

x^2 = xy

Subtract y^2 from both sides

x^2 - y^2 = xy - y^2

Factorise

(x + y)(x - y) = (x - y)y

Divide both sides by (x - y)

x + y = y

Remember x = y, so...

2y = y

Divide both sides by y

2 = 1

 

Come back later, and we'll square the circle...

Maths, like grits, is singular,

though they seem more plural;

yet they make me tingular,

in my pathways neural.
