Cot(x)=-3. find sin(x)
ASHA 777 [7]

Answer:

sin(x)=1/\sqrt10

Step-by-step explanation:

The trigonometric identities involve trigonometric functions. Here we will be using Trigonometric identity

sin²x  = 1 /( 1+cot²x )

now cot(x)= -3

⇒ cot²x= (-3)²

⇒ cot²x= 9

sin²x= 1/( 1+9)

⇒ sin²x = 1/10

taking under root on both the sides we get

√sin²x=\sqrt1/\sqrt10

⇒ sin(x)=± 1/\sqrt10

Step-by-step explanation:

Since we are rounding to the nearest tenth decimal, look in the hundredths place for the number to round up or down with. In this case, it is 9. That means the tenths place would round up to 5.
