John travels a distance of 24km
from twon A on a bearing of 060° to
town B. He then travels a distance
of 18km to town C, which is 30km
east of town A.
(i) what is the bearing of town C from
town B?
(ii) calculate the bearing of town A
from town C?
Let f is a 2^(nd) degree polynomial.
(1/(2πi)) ∫_(∣z∣=2) ((z f ′(z))/(f(z))) dz = 0, and (1/(2πi)) ∫_(∣z∣=2) ((z^2 f ′(z))/(f(z))) dz = −2
If f(0) = 2017, find explicit form of f(z)
let f(α)=∫_0 ^1 ((ln(1+iαx))/(1+x^2 ))dx
1)determine a explicit form of f(α)
2) calculate ∫_0 ^1 ((ln(1+ix))/(1+x^2 ))dx and ∫_0 ^1 ((ln(1+2ix))/(1+x^2 ))dx.
Two radioactive elements A and B
has half lives of 100 and 50years.
Samples of A and B initial contains
equal numbers of atoms.What is
the ratio of the remaining atoms
of A to that of B after 200years?
