  • Question 4/10
    1 / -0

    Solve the given series.

    5, 6, 10, 19, 35, ?

    Solutions

    Add  12 , 22, 32, 42, 52 etc in each consecutive term.

    5 + (12) = 5 + 1 = 6;

    6 + (22) = 6 + 4 = 10;

    10 + (32) = 10 + 9 = 19;

    19 + (42) = 19 + 16 = 35;

    Similarly, 35 + (52) = 35 + 25 = 60.

  • Question 9/10
    1 / -0

    If  x = 3 cos A cos B and y = 3 cos A sin B and z = 3 sin A, then x2 + y2 + z2 is equal to:

    Solutions

    x2 + y2 + z2 = (3 cos A. cos B)2 + (3 cos A sinB)2 + (3sinA)2

    = 9 cos2 A cos2 B + 9 cos2 A sin2 B + 9 sin2A

    = 9 cos2 A (cos2 B + sin2 B) + 9 sin2A

    = 9 cos2 A × 1 + 9 sin2 A         ( Since sin2 B + cos2 B = 1)

    = 9 (cos2 A + sin2 A)

    = 9 × 1 = 9
