Undergrad Proving that a function is a solution to the wave equation

Click For Summary
SUMMARY

The function y(x,t) = ƒ(x/a + t/b), where a and b are constants, is a solution to the wave equation. To prove this, one must substitute the function into the standard form of the wave equation and verify that it satisfies the equation for all functions f. This method of substitution is a definitive approach to confirming the validity of the solution.

How could you that
y(x,t)=ƒ(x/a + t/b),
where a and b are constants is a solution to the wave equation for all functions ,f ?
many thanks.

Relativistic Momentum, Mass, and Energy Momentum and mass (...), the classic equations for conserving momentum and energy are not adequate for the analysis of high-speed collisions. (...) The momentum of a particle moving with velocity ##v## is given by $$p=\cfrac{mv}{\sqrt{1-(v^2/c^2)}}\qquad{R-10}$$ ENERGY In relativistic mechanics, as in classic mechanics, the net force on a particle is equal to the time rate of change of the momentum of the particle. Considering one-dimensional...
