partial fractions and binomial expansion, i think answers are as follows: A=-5/2 B=9/2 -1+7x-22/3x^2 not sure on limit, think some people have something like mod x < 4/3
partial fractions and binomial expansion, i think answers are as follows: A=-5/2 B=9/2 -1+7x-22/3x^2 not sure on limit, think some people have something like mod x < 4/3
mod x <1/2 i believe , since the range of 1/2 falls within the range of 3/4
Not of the original value. That would mean an element would only ever have 2 half lives..
After 100 days you have k^100 lots of the original value left. After 200 days you have (k^100)^2 of the original value. So therefore you loose (0.8)^3 over 300 days, given that k^100 is approximately 0.8 because you had roughly 8=(k^100)*10
