Question
A wave is represented by an equation $\text{y}=\text{c}_1\sin(\text{c}_2\text{x}+\text{c}_3\text{t}).$ In which direction is the wave going ? Assume that $c_1, c_2$ and $c_3$ are all positive.

Answer
Equation of the wave is.$\text{y}=\text{c}_1\sin(\text{c}_2\text{x}+\text{c}_3\text{t})$
When the variable of the equation is $(c_2x + c_3t),$ then the wave must be moving in the negative x-axis with time t.
When the variable of the equation is $(c_2x + c_3t),$ then the wave must be moving in the negative x-axis with time t.
