Document Summary
Mth 140 midterm 2 - (solutions) (multiple choice question) let be a real constant. The second derivative of f (x) = sin (e x) is: f (x) = 2e x(cos(e x) e x sin(e x), f (x) = 2e x(sin(e x) e x cos(e x), f (x) = 2e x sin(e x, none of these, f (x) = sin(e x) Marks (multiple choice question) the derivative of xx2 is: 3: f (x) = xx2 ln x, f (x) = xx2(x2 ln x + 1, f (x) = xx2( x2, f (x) = x2xx2 1 x + 2x ln x, none of these. Write the (capital) letter of the answer in this box. Only the answer in the box will be marked. Given the function f (x) = x + 1 + = lim h 0 h f (3 + h) f (3) ( (3 + h) + 1 + H + 4 2 lim h 0 h.
