CMAT 2017 Solved Question Paper

Question : 20 of 100

Marks: +1, -0

If sin θ + cosec θ = 2, then the value of

{\sin}^{100}

θ +

{cosec}^{100}

θ is

Solution:

1/{\sim \θ

= 2
Let , sin θ = 1
⇒ 1 + 1 =2
It is in the form , x +

1/\x = 2 \then, \x^\n + 1/\x^\n

= 2
Therefore,

{\sin}^{100}

θ +

{cosec}^{100}

θ = 2
