For the equation ax2 + bx + c = 0,
(a + b)n = an +
an–1 b +
an–2 b2 + … +
an–r br + … + bn,
where n is a positive integer and
sin2 A + cos2 A = 1.
sec2 A = 1 + tan2 A.
cosec2 A = 1 + cot2 A.
Formulae for ∆ABC
a2 = b2 + c2 – 2bc cos A.
∆ = bc sin A.
(n – r)!r!
1 Write down the inverse of the matrix
and use this to solve the simultaneous equations
4x + 3y + 7 = 0,
7x + 6y + 16 = 0.
Find the first three terms in the expansion, in ascending powers of x, of (2 + x)6 and hence obtain the
coefficient of x2 in the expansion of (2 + x – x2)6.
