Tiny script for counting examples of several math situations. All functions expect valid input.
It's possible to include it directy:

countiny_quad(a, b, c, x);
A
,B
andC
- CoefficientsX
- A root number (1 or 2)
countiny_fctr(a);
countiny_comb(n, k);
- Numerator:
n!
- Denominator:
k! * (n-k)!
countiny_vari(n, k);
- Numerator:
n!
- Denominator:
(n-k)!
countiny_alog(a, x);
- Base:
a
- Argument:
x
- Numerator:
log(x)
- Denominator:
log(a)
countiny_root(x, n);
countiny_dgrd(deg);
countiny_dgrd_pi(deg, pi_sign);
deg
- inputpi_sign
: logic variable (true
orfalse
)- If pi_sign is true, output will look like
2π
- If not, output will look like
2
countiny_rddg(rad);
a
- A whole numberb
- A value of percentagesc
- A part of a whole number
countiny_perc_part(a, b);
countiny_perc_whol(b, c);
countiny_perc_pers(b, c);
countiny_rang(a, min, max);
a
- the numbermin
- minimal value in the rangemax
- maximal value in the range- This function returns
true
orfalse
countiny_nrnd(num, dec);
num
- an input numberdec
- how many decimal places
