The simultaneous equations in x, y,
(cosθ)x - (sinθ)y = 2
(sinθ)x - (cosθ)y = 1are solvable
(a) for all values for θ in the range 0 ≤ θ ≤ 2π
(b) except for one value of θ in the range 0 ≤ θ ≤ 2π
(c) except for two values of θ in the range 0 ≤ θ ≤ 2π
(d) except for three values of θ in the range 0 ≤ θ ≤ 2π

In exam paper the second equation was plus not minus , but if it was as you sent it both minus it looks as if it cant take 2 values which are pie/4 and 5pie/4 not sure thoughLast reply 6 hours ago
