Calculate cos (79) cos is found using Adjacent/Hypotenuse Determine quadrant: Since 0 ≤ 79 ≤ 90 degrees it is in Quadrant I sin, cos and tan are positive. Determine angle type: 79 < 90°, so it is acute cos (79) = 0.19080899692312 Write cos (79) in terms of sin Since 79° is less than 90... We can express this as a cofunction cos (θ) = sin ...

The cos of 79 degrees is 0.19081, the same as cos of 79 degrees in radians. To obtain 79 degrees in radian multiply 79° by π / 180° = 79/180 π. Cos 79degrees = cos (79/180 × π). Our results of cos79° have been rounded to five decimal places.
