cos 90° = sin 0° = 0. So, for cos, it will be like. cos -30 degrees sin 30 = cos 60. sin 45 = cos 45. sin60 = cos 30. sin 90 = cos 0. Hence, all the cos values can be filled now.
√3 2 3 2. The result can be shown in multiple forms. Exact Form: √3 2 3 2. Decimal Form: 0.86602540… 0.86602540 …. 47 rows cos (30° − 45°) cos (30 ° - 45 °) Subtract 45 45 from 30° 30 °.
cos 30° = sin 60° = √3/2.
sin30=cos60=1/2. Quick way to Now you have a 60 degree angle and a 30 degree angled triangle. sin 30° = cos (90 - 30)° = cos 60°.
Cosines apply to angles. Wolfram guesses you mean 30 degrees if you ask it for cos(30) but Google guesses you mean 30 radians.
The value of Cos 30 degree is √3/2 Another Different form of Cos 30° is cos pi/6 or cos π/6 Hence, cos pi/6 = √3/2 Cos 30° = √3/2 is an irrational number and it equals 0.8660254037 approx. And then, the exact value of cos 30 degrees is written as 0.8660 approx. √3/2 is the value of Cos 30° which is a trigonometric function of a particular angle.

First, we can evaluate the functions of 60° and 30°. Example 1. Evaluate cos 60°. Answer. For any problem involving a 30°-60°-90° triangle, the student should not use a table. The student should sketch the triangle and place the ratio numbers. Since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60
