k = 0; % values range from -10 to 10 in 0.1 steps. Set your boundaries
t= t; % values range from -10 to 10 in 0.1 steps. Set your boundaries
x = 1,000,000 Pi.*u./v; % x depends on the values of u and v
You will end up with an array ( x ) of values for x that fulfil the condition imposed by your equation.
