    Solutions

  • Question 4/10
    1 / -0

    If sin (sin-1 1/7 + cps-1 x) = 1, then x is equal to

    Solutions

  • Question 5/10
    1 / -0

    If (√8+i)50 = 349 (a + ib), then a2 + b2 is

    Solutions

  • Question 6/10
    1 / -0

    If the roots of the equation ax2 + bx + c = 0 are of the form k+1/k and k+2/k+1 then (a + b + c)2 is equal to

    Solutions

  • Question 7/10
    1 / -0

    Solutions

  • Question 8/10
    1 / -0

    The coefficient of x5 in (1+2x+3x2+……….up to infinite term)-3/2 is

    Solutions

    (1+2x+3x2+………)–3/2

    =((1–x)–2)–3/2

    = (1 − x)3 = 1 − 3x + 3x2 − x3

    ∴coefficient of x5 = 0.
