Calculate cos(pi/6) cos is found using Adjacent/Hypotenuse. Determine quadrant: Since 0 ≤ 0 ≤ π/2 radians it is in Quadrant I. sin, cos and tan are positive. Determine angle type: 0 90°, so it is acute. cos(π/6) = √ 3 /2. Excel or Google Sheets formula: Excel or Google Sheets formula:=COS(PI()/6) Special Angle Values
The COS function returns the cosine of an angle provided in radians. In geometric terms, the cosine of an angle returns the ratio of a right triangle's adjacent side over its hypotenuse. For example, the cosine of PI()/6 radians (30°) returns the ratio 0.866.
For example, to take the sine of cell A1, enter =SIN(PI()/180*A1) into the formula bar. Our example worksheet contains a spreadsheet to calculate the sine, cosine and tangent for 0 to 2π. Since the angles are already in radians, it’s straightforward to do these calculations.
