It is probably the best strategy to try to rewrite the formula with algebra. Other than that my question would be the same as Darova: what have you tried so far?

i am a PhD student. I am writing a code on a wave spectrum and this equation is a part of it. I cannot solve this one algebraically. though i have the results using function option. bt i want the algebraic one proceed with my code

Hi A. Hossain
Try this:
clear; clc;
syms w d k
d=100
g=9.8
for w=0:0.01:10
fprintf('----- w = %f -----\n', w);
eq=w.^2==g*k*tanh(k*d)
vpasolve(eq)
fprintf('\n\n');
end
Of Course, it does not provide an analytical solution, but a numerical one.
