Unformatted text preview: dP ; then evaluate all the partial derivatives to make this expression specific. 3. (6) In problem 11, you had to use the chain rule to obtain the partials ( ∂ f / ∂ x ) t and ( ∂ f / ∂ t ) x , when f was defined as f ( x + ct ). Suppose now that f = f ( u ), with u = x 2 + 3 t . Obtain ( ∂ f / ∂ x ) t , ( ∂ 2 f / ∂ x 2 ) t , and ( ∂ f / ∂ t ) x . [Express these in terms of f' ( u ) and f'' ( u ).]...
