For the traveling wave described by the formula(adsbygoogle = window.adsbygoogle || []).push({});

y(x,t) = Asin(kx-wt)

Then the wave is traveling in the +x direction. True or false?

In the physics textbook I have, it describes a traveling wave by y(x,t) = Acos(kx-wt), using COS instead of SIN. Is there a difference between these 2 formulas? If there is no difference then shouldn't the statement above be true?

Also

Would the wave Asin(kx+wt) travel in the opposite direction of Asin(kx-wt)?

Thank you for your help.
