"Why are the values opposite in the form (y -y_1)=m(x - x_1)?"
a little history on the calculation of pi.
Some r code:
approx.pi<-function(x){
half=x/2
ad=sqrt(1-half^2)
de=1-ad
be=sqrt(de^2+half^2)
print(be)}
for(i in 1:10){empty=c(empty,approx.pi(eight)*2^(i+1))
+ eight=empty[i]/2^(i+1)}
function notation:
why we use it
how it can get complicated (functions inside of functions, oh my!)
domain and range
