√3/2 is the value of Cos 30° which is a trigonometric ratio or trigonometric function of a particular angle. Cos 30 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. color(brown)(cos (-30) = cos 30 = cos (pi/6) = sqrt3 / 2 = 0.866 To get exact value of cos(-30) http://www.ask-math.com/all-sin-cos-tan-rule.html cos (-30) is in IV quadrant where only cos and sec are positive. Hence cos(-30) = cos 30 = cos (pi/6) From the above table, color(brown)(cos (-30) = cos 30 = cos (pi/6) = sqrt3 / 2 = 0.866 Exact values of sin(30), cos(30), tan(30), csc(30), sec(30), cot(30), Find exact values of all trigonometric functions when the angle is 30 degrees,blackpenr All the cos values are filled in opposite order starting from sin 0 to sin 90. I mean to say that.

Tan 30 Degrees Value.

750°, calculate cos 750° as cos (750 Mod 360)° = cosine of 30°, or look it up with our form. color(brown)(cos (-30) = cos 30 = cos (pi/6) = sqrt3 / 2 = 0.866 To get exact value of cos(-30) http://www.ask-math.com/all-sin-cos-tan-rule.html cos (-30) is in IV quadrant where only cos and sec are positive. Hence cos(-30) = cos 30 = cos (pi/6) From the above table, color(brown)(cos (-30) = cos 30 = cos (pi/6) = sqrt3 / 2 = 0.866 All the cos values are filled in opposite order starting from sin 0 to sin 90.

(ii) We observe that sin 30° and cos 60° are equal. Also sin 60° and cos 30° are equal. ( iii) The value of reciprocal Sum of the angles in a triangle is 180 degree wo Find the Exact Value cos(30 degrees ) The exact value of is . The result can be shown in multiple forms. Exact Form: Cos 30 degrees is written as cos 30° and has a value in fraction form as √3/2.

If the angle of a right triangle is equal to 30 degrees, and then the value of cosine at this angle i.e., the value of Cos 30 degree is in a fraction form as √3/2. $\cos{(30^°)} \,=\, \dfrac{\sqrt{3}}{2}$ The value of cos of angle $30$ degrees is equal to $\dfrac{\sqrt{3}}{2}$ in fraction form exactly. It is an irrational number and equals to $0.8660254037\ldots$ in decimal form and the same value is considered as $0.866$ approximately in mathematics. The value of cos $30^°$ is usually called as The exact value of cos(30°) is √(3) / 2. We can find this using the cosine half-angle identity property which is as follows: If an angle, See full answer below. The Trignometric Table of sin, cos, tan, cosec, sec, cot is useful to learn the common angles of trigonometrical ratios from 0° to 360°. Select degrees or radians in the drop down box and calculate the exact cos 30° value easily.
