You will not be able to get an explicit expression for k.
I have the equation y = 1/k * ln(cosh(SQRT(g*k)*t))
My goal is to solve for k. This is for aerospace engineering and "k" includes a variable that I need.
I have rearranged two ways already:
1) k = (acosh^{2}(e^{yk}))/(g*t^{2})
2) k = ln(cosh(SQRT(g*k)*t))/y
I have NO IDEA as I am only a freshman. How do I get k to a single side? I would greatly appreciate help with this.
Best regards,
Dwight
