Question

Sino coseco + sin²o cosec²o + + sin⁹o cosec⁹o =?​

Answer 1

Answer:

The final answer is 3.

Step-by-step explanation:

this is a basic question of trigonometry where o is the angle in between now we know that cosec is reciprocal of sine

in the question sine and cosec are in multiplication relation

again win the question we are given that Sino coseco + sin²o cosec²o + + sin⁹o cosec⁹o

Now Sino coseco = sino *1/cosec o =1

Similarly sin²o cosec²o = 1

sin⁹o cosec⁹o = 1

now if we add all the three well left with 1+1+1=3

Answer 2

Answer:

3

Step-by-step explanation:

sinФ cosecФ + $sin^2$Ф $cosec^2$Ф + $sin^9$Ф$cosec^9$Ф

cosecФ = $\frac{1}{sin}$Ф

sinФ×$\frac{1}{sin}$Ф + $sin^2$Ф×$\frac{1}{sin^2}$Ф + $sin^9$Ф× $\frac{1}{sin^9}$Ф

=> 1+1+1

=> 3
