Homework Statement
tanh{[(2 *g*t)/(c)]+[(2*g*exp(-rt))/(r*c)]-[(2*)/(r*c)]} in terms of t
Homework Equations
when I plug into maple I get -(1/4)*c*ln(tanh(2*g*(t+1/r(e^(-rt))-1/r)/c)-1)/g-(1/4)*c*ln(tanh(2*g*(t+1/r(e^(-rt))-1/r)/c)+1)/g
The Attempt at a Solution
This cannot be right.. I always thought the integral of tanh was log(cosh)? Plus when I enter all the constants and evaluate at the bounds (g=9.8, r=1/94670777.9, t=3.156*10^8, c=3*10^8) I get an answer of [(ln(0)+ln(2))-(ln(-1)+ln1)] Which is an impossible answer, even if I omit the undefined ones, I still get an answer that should not be related to relativity..
Any help would be greatly appreciated! Thank you so much!
