Are you sure there is only one solution for cos(x)=0?

both have an infinite number of solutions. cos(x^2) = 0 has broader distribution of solutions compared to the linear and equally spaced solutions of cos(x) = 0. cos(x^2) = 0 is more dense in unique values.

But can one argue that one infinity is larger than the other? They're both infinite...
