Very carefully

how does this work?

This is why calculus should be a requirement for this board

Start by checking the quality of the wood.

REEEEEE

we start by assuming that [math] f(x) [/math] is a continuous function over [math] [a,b] [/math]
Then we say that [math] f(x) = 5 [/math]

Now given that
[math] log_{a}(x) = f(x) [/math]
Then [math] log_{a}(x) = 5 [/math]

How the fug would you get x with a calculator, especially with log base-e?

>>7969753
Most calculators have a log function.

>>7969580
holy shit why are you so mad?

integrals

how does this work?

>>7969580
[math]f(x)\approx f(x_0) + \frac{df(x)}{dx}\Delta x[/math]

Goddammit, REEE guy, nobody likes your autistic unfunny bullshit, not in /fit/, not here, and not anywhere.

I think taylor series may work:

write log (x) as log (y*10^k) where 0<y<=1:

[eqn] log(x) = log(y*10^{k}) = log(y) + log(10^{k}) = log(1+(y-1)) + k \approx k+z − \frac{z^{2}}{2}[/eqn]

where z=y-1
