Here,  [√(y +1) - √(y - 1)]/ [√(y + 1)+√(y - 1)] Multiplying and dividing by √(y + 1) - √(y - 1), we get  = [√(y +1) - √(y - 1)][√(y + 1) - √(y - 1)]/ [√(y + .....

Here,  Radius = OA = 13cm Length of chord = 24cm So, AP = 24cm/2 = 12cm            [ Perpendicular drawn from the centre bisects the chord.] Now, in right angle triangle AOP,  OP = √[ .....

Here, LHS =  sec260o - tan260o          = (2)2 - (√3)3              [ Since, sec60o = 2 & tan60o = √3.]         = 4 - .....

We know, π = 180o  So, given expression becomes,       Sec245o .sec260o(cosec30o - cosec90o) = √22 . 22(2 - 1)     [ Since, using value of sec45, sec60 , cosec30 & .....

Proved.Here,  LHS = cosA/secA + sinA/cosecA          = cosA.cosA + sinA.sinA      [ Since, 1/secA = cosA & 1/cosecA = sinA.]        = cos2A + sin2A       .....

Here,  (2√3 -3√2) / (2√3 +3√2) Multiplying and dividing by (2√3 -3√2) we get, (2√3 -3√2)(2√3 -3√2)/ [(2√3 +3√2)(2√3 -3√2)] = (2√3 .....
