Question

If sine alpha +cosec alpha=2 find the value of sine n alpha +cosec n alpha n belongs to z
​

Answer 1

Step-by-step explanation:

Hello m.r

sinα+cosecα=2

sinα+

sinα

1

=2

sin

2

α+1=2sinα

sin

2

α−2sinα+1=0

(sinα−1)

2

=0

sinα=1

hence,

cosecα=

sinα

1

=1

now,

sin

n

α+csc

n

α=(1)

n

+(1)

n

=1+1=2
