1RM = 100 * 245 / (48.8 + 53.8 * EXP(-0.075 * 5) )

i have no fuckin idea what EXP is.

e = mc²

i have no fuckin idea what EXP is.

EXP means (number)^10

and it's pronounced "exponent"
so, in your example it would be: (-0.075*5)^10
calculator tells me it's around 0.00055

alexg · 04-27-2004, 01:12 PM

i'm not 100% sure though

Wish you were around when I was failing my calculus test. . .

i don't think so

EXP(number) means, the number e raised to the power of "number"

EXP(-0.075 * 5) = e ^ (-0.075 * 5) = 0.687289279

That's what I was thinking but if this is right then why is there the * immediately before EXP

1RM = 100 * 245 / (48.8 + 53.8 * EXP (-0.075 * 5) )

Wilber · 04-27-2004, 01:36 PM

If 1RM mean 1 repetition per minute then EXP means
a weight lifting idiot is inventing their own math. There is no such thing as EXP in math.

In scripting languages exp is sometimes used but I doubt that applies here.

Those kinds of people should keep spending their time looking in mirrors
and less time posting math formulas. Brawn is brawn and brain is brain,
never try to meld the two.

why can't there be?
I don't know what the formula is all about, but what's the problem. It's (Number_A)*(Number_B)^10

fktup · 04-28-2004, 07:40 AM

EXP (-0.075 * 5) = 0.687289278790972

1RM = 100 * 245 / (48.8 + 53.8 * EXP (-0.075 * 5) ) = 285.627137963414

correct -- I really wish I would have taken classes with Lane... smart kid. Oh wait. I did.

04-28-2004, 07:47 AM

exp(5) = e^5.

According to Euler,

e = 1 + 1/1! + 1/2! + 1/3! + ... and that e is the limit of (1 + 1/n)^n, as n approaches infinity... and approximates to roughly 2.71.

milambur · 04-28-2004, 08:20 AM

Yup, Lane got it right, it is called the exponential function and is usually denoted e^x.

bingo

exp(-.075 * 5) = 0.687289279

kowntafit · 04-28-2004, 09:52 AM

I'm no maths expert but I had to do calculus as part of my uni course. I thought EXP stood for 'exponential', not exponent, but they may be the same thing. I would say that the exponent is probably the thing in the brackets as apposed to the whole thing, straight out of my ass though. I would do e^(-.075 * 5). e^()seems to be pretty cool when it comes to calculus, you cant go wrong with a bit of e^().

galleryseek · 04-28-2004, 09:56 AM

i found out the answer to that equation: (fktup was right)

1RM = 100 * 245 / (48.8 + 53.8 * EXP(-0.075 * 5)

1RM = 285.6

Wilber: heh, 1RM = One Rep Max.. that formula is stating if a person lifted 245 5 times, he could lift 285 once. which sounds about right. and i pasted that coding directly into PHP and worked perfectly. ;) so you're pretty off bud.

KRosh · 04-28-2004, 10:02 AM

EXP or e^() is the Exponent function

alexg · 04-28-2004, 10:03 AM

i guess i was wrong then
well, I said I wasn't 100% sure

that's right, and nothing else....
the exp stands for e^(number)
e is euler...e^1 is the euler's number_: 2.7182818

swedguy · 04-28-2004, 10:12 AM

The math:exp function returns e (the base of natural logarithms) raised to a power.

The return value is the power of the constant e. The constant e is Euler's constant, approximately equal to 2.178.
