Question

If Sin Ɵ + Cosec Ɵ = -2 find the value of Sin^5Ɵ – Cosec^5Ɵ.​

Answer 1

Step-by-step explanation:

SinA+cosecA= -2

sin²A+1= -2sinA

Sin²A+2sinA+1=0

(sinA+1)²=0

sinA+1=0

sinA= -1

Sin⁵A - cosec⁵A

=(-1)⁵+(-1)⁵

= -1-1 = -2

Hope this helps you.

Answer 2

Answer:

0

Step-by-step explanation:

from the given equation sin theta =1

   theta= 90

   5*theta=450

   sin 5*theta=1

   sin 5*theta-cosec 5*theta=1-1=0
