Contrast waves in the electromagnetic spectrum with water waves in the ocean.
Let f : R → R be a continuous function and g : R → R be a Lipschitz function. Would you help me to prove that the system of differential equation x ′ = g ( x ) y ′ = f ( x ) ywith initial value x ( t 0 ) = x 0 and y ( t 0 ) = y 0 has a unique solution.Could I prove the uniqueness solution of x ′ = g ( x ), x ( t 0 ) = x 0 by Gronwall Inequality first then use the result to prove the second?

Discrete math: proofsFor any three integers x, y, and z, if 𝒚 is divisible by x and z is divisible by y, then z is divisible by x.definition: An integer n is divisible by an integer d with D ≠ 0, denoted d|n, if and only if there exists an integer k such that n = d k.Can anyone help, with this problem I don't know how to approach it should I use proof by cases where every number is odd or even. Should I use direct proof or indirect proof?
