This value is taken from the unit circle a commonly used device in mathematics that assigns values to the trigonometric functions of sine and cosine. Question 14 value of cos 0.

### Therefore the value of cos 90 degrees is.

**Cos 90 is**. Remembering the table 0 30 45 60 90 sin 0 1 2 1 2 3 2 1 cos 1 3 2 1 2 1 2 0 tan 0 1 3 1 3 not def. Cos 90 putting values 1 3 2. The cosine cos of 90 degrees is zero.

Cos 90 θ o f o e cos 90 θ d c o c of dc and oe oc since ocd oef cos 90 θ sin θ. Cos 30 cos 45. As the third side of the triangle does not exist length is 0 the cosine equals zero 0 divided by the length of the hypotenuse equals 0.

Tan 90 θ f e o f. The cosine of a 90 degree angle is equal to zero since in order to calculate it we would need a triangle with two 90 degree angles which is the definition of a straight line. Cos 30 cos 45.

Cos 90 is. Cos 90 0 it is observed that the values of sin and cos functions do not change if the values of x and y are the integral multiples of 2π.
