Thread: solvable?

Is the neperian logarithm ( ) base ?
And when you say constant, you mean known ? Otherwise you could just sieve, if you always have the same values except ...

yes, e is ln based. And by constant I simply mean not functions of anything else.

So, I am looking to solve for t in terms of the other variables.

This function is a result of setting two equations equal to each otehr so I am trying to solve at what time t they become equal for different parameters.

It may be useful to back up and look what A means for C, for instance. You might be able to find common factors, or even better, you may be able to substitute ... So can you post the integrality of the calculations you made ? There might be something you didn't see that makes the solving obvious.

Are there any conections between the constants? What is the context of this problem?

You might find it advantageous to post the original question.

ok, here is whre i got that form from, but realize that it does not belong in this forum. As I say in the paper, even if there is another way to go about it, i am curious to know if equations of that form can be solved.

Ouch this is too complex for me

These problems are generally solved numerically.
