Help needed with a trigonometry question: Show that: cos 3x = 4 cos3x - 3 cos x I expanded the LHS using the sum of 2 angles and got cos 3x = cos3x - 3cos x sin x :awesome::haha::tongue::)

i) Factorise x3 + y3 ii) Hence find the value for x2 + y2 if: x + y = 7 and x3 + y3 = 19 for the first part I got: x3 + y3 = (x + y)(x2 - xy + y2) For the second part of the question I got 127/7 but i'm not sure if it's correct Here is the working out: (x + y)2 = 72 = 49 (x + y)2 = x2 + y2 +...
