If x = cosecθ - sinθ and y = secθ - cosθ, then the relation between x and y is

The distance between two pillars is 120 metres. The height of one pillar is thrice the other. The angles of elevation of their tops from the midpoint of the line connecting their feet are complementary to each other. The height (in metres) of the taller pillar is (Use : √3 = 1.732)

If cosθ = x2-y2x2+y2, then the value of cotθ is

The value of the expression 2(sin6θ+cos6θ) - 3(sin4θ+cos4θ) + 1 is

If cosx.cosy + sinx.siny = -1 then cosx + cosy is

If sin P + cosec P = 2, then the value of sin7P + cosec7P is

If secA + tanA = a, then the value of cosA is

PQ and RS are common tangents to two circles intersecting at A and B. AB, when produced both sides, meet the tangents PQ and RS at X and Y, respectively. If AB = 3 cm, XY = 5 cm, then PQ (in cm) will be
