Section A [45 marks]Answer all questions in this section.
1 Express in partial fractions. [5 marks]
2 Express in the form where R is a positive and is acute. Hence, solve the equation for . [6 marks]
3 Given that where , find x. [7 marks]
4 Find the set of values of x which satisfies . [7 marks]
5 By using the substitution and , where that , show that
. [3 marks]
Hence, or otherwise, by using the substitution , show that . [4 marks]
6 The polynomial , where a and b are real constants, is divisible by .(a) Find a and b. [5 marks](b) For these values a and b, factorise p(x) completely. [2 marks](c) Show that 2 is a zero of the polynomial . Hence, solve the equation
by using the polynomial p(x). [6 marks]
