What angle is 5pi 12?
75°
In our case: ad=512π⋅180°π=75° .
How do you solve Cos 5pi 12?
The value of cos 5pi/12 can be calculated by constructing an angle of 5π/12 radians with the x-axis, and then finding the coordinates of the corresponding point (0.2588, 0.9659) on the unit circle. The value of cos 5pi/12 is equal to the x-coordinate (0.2588). ∴ cos 5pi/12 = 0.2588.
How do you evaluate sin 5pi?
The value of sin 5pi can be calculated by constructing an angle of 5π radians with the x-axis, and then finding the coordinates of the corresponding point (-1, 0) on the unit circle. The value of sin 5pi is equal to the y-coordinate (0). ∴ sin 5pi = 0.
What quadrant is 5pi 12 in?

How many degrees is 17pi 12?
To convert from radians in degrees we have to multiply by 180π . ⇒−17π12=−17π12⋅180π=−255 degrees.
What is a sum or difference formula?
The difference formula for cosines states that the cosine of the difference of two angles equals the product of the cosines of the angles plus the product of the sines of the angles. The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle.
Where are identities used in trigonometry?
Trig identities are trigonometry equations that are always true, and they’re often used to solve trigonometry and geometry problems and understand various mathematical properties. Knowing key trig identities helps you remember and understand important mathematical principles and solve numerous math problems.
What is sin 5π 12 = √6 +√2 4?
Actually it is very easy to find that sin( 5π 12) = √6 +√2 4. You use the formula for the sine of a sum: Think of a pie divided into twelve slices. Three of them form one quarter, two more form one sixth of the pie. So, thinking of the “pie” as π: 5π 12 = π 4 + π 6.
