I can’t solve problems about parent/daughter isotopes for this concordia plot because I don’t know calculus!! Help me!!
For example, where λ is the decay constant of 238U (1.55x10^-10)
and time would be 500,000,000 years,
and the equation I am trying to use is 206pb/238u = e^λt - 1, to find 206pb/238u amount in an ideal condition given a certain time.
Please help I really don’t know what I’m doing
