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 $\pi$ / 180° = 79/180 $\pi$. Cos 79degrees = cos (79/180 × $\pi)$.
