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.
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
9 paź 2024 · The PI () function returns the value of pi, and dividing it by 2 gives you the value of π/2. This will return the value of 1, which is the sine of 90 degrees. Or you can convert 90 degrees to radians using the formula below, =SIN(RADIANS(90)) //returns 1.
