Hi, Let v(x,t) = u(x+ct,t). Find partial of v with respect to x, second partial of v with respect to x and the partial with respect to t. I'm just confused with the t's acting as x+ct and t by it self. Thanks

How would I substitute those values into the equation: partial u with respect to t - k*second partial u with respect to x + C*partial u with respect to x = 0. Here k and C are constants.
