Question from Brandi, a student: Objective: solve for t, where r = 0.05 0 = (1/t) - [ln(1+r) ln(t)] Thanks, I am stumped.... |
Hi Brandi,
Let a = ln(1 + 0.05) which is approximately 0.4879 and your equation becomes
(1/t) - a ln(t) = 0
There is no simple way to solve this equation for t, the best I can do is offer an approximation. I would try the Newton-Raphson method on this problem.
I hope this helps,
Penny
