Question

If Sin ø = 1/3 then find the value of 2 cot² ø + 2.​

Answer 1

Step-by-step explanation:

sin(A) = 1/3

=> cot(A) = √8/1

so , 2cot^2(A) + 2 = (2*8) + 2

= 18

hope it is helpful.....

Answer 2

Answer:

18

Step-by-step explanation:

Sin theta =1/3=p/h

So,b=2root2

Now, cos theta =b/h=2root2/3

So, tan theta=sin theta/cos theta=1/2root2

Therefore,cot theta=2root2

Hence,2 cot^2theta+2=>2×8+2=16+2

=>18
