Hi Can you please graph Question - B with step by step how you could you get coordinate. Please show step by step answer. 

 

Just do question B only

Infinite String: consider the initial/boundary value problem

where f and g are two given twice differentiable functions. We
showed in class that this problem is solved by he d'Alembert's
solution
