...flow in an artery of vein..? The half-life of sodium-24 is 14.9 hours. Suppose that a hospital buys a 50-gm sample of sodium-24.
a) How much of the sample will remain after 46 hours?
b) How long will it be until only 1 gm remains?
2) Prove the following identity
sec x / sin x - csc x / sec x = tan x
