I can answer almost anything that is sent in. If I can't, I'll let you know, but I don't expect that to happen much. |
Hello Kevin This question is really about the factor theorem. Do you remember it? A polynomial p(x) has the factor (x-a) iff p(x) = 0 has a root x = a. Now, a polynomial of the form p(x) = a^(2k+1)
Hello Asad I hope these aren't homework problems. It's OK if you have managed to do 1 to 18 yourself. 19. You need to multiply out N and D to get (x^2+3x+2)/(x^2-3x+2) Then use the quotient rule to
Hello Asad These aren't problems but routine examples. I suspect you haven't studied worked examples of the techniques. OK that's the lecture over. 2. The method here is to divide N and D by x^2.
Hello Asad You don't say what to differentiate with respect to, but I shall assume it is x. 9. (1/a)(2x/b - 2/a + d/x^2). It is arguable what the simplest expression is here. It may be 2x/(ab)
Hello George You have left it late. Why didn't you query days ago. It is past midnight here in the UK and though I can answer all your questions, I don't have time. So I'll give you half an hour
