(1 point) a. Assuming a, b and k are constants, calculate the following derivative. b. Find a value of k so that EE ki is a solution to x k = c. Find a value of k so that ek is a solution to x k = d. Write down the general solution in the form x1 (t) =? and x2(t) =?, i.e., write down a formula for each component of the solution. Use A and B to denote arbitrary constants. x1 (1) = X2 (1) =
