4. Find and explain the error in the following de = (In |x - 31) |% = In |6 - 3) - In |0 - 3 = In(3) - In(3)5. Find f(x) where f(x) = In Jr). Note: in this context r is a real number except it is not zero. 6. State the definition of the derivative of a function f. Use the definition of the derivative to In (1 + 1) evaluate lim if it exists. If the limit does not exist, explain why T-409. Find p(t) if p"(t) = 2c' + 4 cos(t), p(0) = 0 and p'(0) =0. Explain why the expression you found for p(t) is correct
