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 Given that A =
, find A–1 and hence solve the simultaneous equations
2x + 3y + 4 = 0
–5x + 4y + 13 = 0.
2 Given that
, where a and b are integers, find, wi
