what kind of math are you doing right now

Learning addition right now, it's tough stuff man

i haven't been in a math class since 10th grade

[pch]

i dont pay attention in my algebra 2 class in the slightest, still pass with like a B cause the teacher is cool

[Teneksi]

None

and I couldn't be happier

right now we're doing exponential growth and decay, it's pretty simple
decay
y=n(r-1)^t
growth
y=n(r+1)^t

What the forget? y = nr² -2nr + n is not the equation for exponential decay. Exponential decay is y = a*b^x where 0 < b < 1.

just finished limits in calculus

I'm re-taking Calculus I because I was not satisfied with my score. Going over dumb review over identifying functions and doing difference quotients right now since we just started on Monday.

f(x+h) - f(x)
        h

f(x) - f(a)
   x - a

[ultimamax]

multivariable calculus

we are reviewing taylor polynomials right now, presumably to expand upon them

[carolcat]

pre-ap algebra 2, currently working on rational reciprocal function families

[Cubed Root]

trig

[Ravencroft·]

Finished Differential Equations (Calc IV) a few semesters ago.

[sorrel]

calc doing basic differential equations for ln and log functions

[The Resonte!]

the mathematics of quantum neutrino fields

What the forget? y = nr² -2nr + n is not the equation for exponential decay. Exponential decay is y = a*b^x where 0 < b < 1.

then what the forget were we doing then because that's how we were solving the decay problems

y = nr² -2nr + n

wait wait wait where are you getting this

we solve the problems by being given a starting number and a percent, put the starting number for the n and then putting the percent in a decimal. so it'd be like
y=4000(1-.045)^t
y=4000(.955)^t
y=3381.49

atleast that's how i think it works, i'll have to look at my notes again to make sure

Pre-AP Geometry. Last thing we did was 3 days ago, I forgot if it was Angles of Elevation/Depression or the Laws of Sines/Cosines.
