## How do you deal with Sin 7pi 6?

The value of sin 7pi/6 can be calculate by constructing an angle of 7π/6 radians with the x-axis, and then finding the works with of the corresponding suggest (-0.866, -0.5) on the unit circle. The worth of sin 7pi/6 is same to the y-coordinate (-0.5). ∴ sin 7pi/6 = -0.5.

## What is cosine that pi end 6?

The specific value of cos(π6) cos ( π 6 ) is √32 .

## How perform you find sin pi 6?

The worth of sin pi/6 can be calculation by constructing an angle of π/6 radians through the x-axis, and also then detect the works with of the corresponding suggest (0.866, 0.5) ~ above the unit circle. The worth of sin pi/6 is same to the y-coordinate (0.5). ∴ sin pi/6 = 0.5.

## What is Cospi?

The value of cos pi is -1. Cos pi can likewise be expressed utilizing the indistinguishable of the offered angle (pi) in levels (180°). We know, utilizing radian to level conversion, θ in degrees = θ in radians × (180°/pi) ⇒ pi radians = pi × (180°/pi) = 180° or 180 degrees. ∴ cos pi = cos π = cos(180°) = -1.
