What is the value of sine 60 degrees?
The sine of 60 degrees or π/3 radians is exactly equal to one-half the square root of three. The sine of an angle is defined from a right triangle. That is, the sine of 60 degrees or π/3 radians is equal to half the square root of 3.
What is the sine and cosine of an angle?
The sine of the angle is given by the ratio «opposite over hypotenuse.» The cosine is given by the ratio «adjacent to hypotenuse». The tangent is given by the relation «opposite between adjacent».
What is the cosine of 150?
The cosine of 150 degrees or 5π/6 radians is exactly equal to half the square root of negative 3.
How to get the cosecant of 60 degrees?
The exact value of csc(60°) csc ( 60 ° ) is 2√3 . Multiply 2√3 by √3√3 .
What is the cosine of 60 degrees?
The cosine of 60 degrees or π/3 radians is exactly equal to one-half, 1/2. The cosine of an angle is defined from a right triangle.

How do you get the csc?
The cosecant is the reciprocal trigonometric ratio of the sine. It is the reciprocal or the multiplicative inverse of the sine, that is csc α · sin α=1. The cosecant of the angle α of a right triangle is defined as the ratio of the hypotenuse (c) to the opposite leg (a).
What is the value of the cosine?
The cosine function is one of the three main trigonometric functions. The cosine of an angle can be defined from a right triangle. In a right triangle, one of the angles is equal to 90°.
