Calculate cos(48) cos is found using Adjacent/Hypotenuse. Determine quadrant: Since 0 ≤ 48 ≤ 90 degrees it is in Quadrant I. sin, cos and tan are positive. Determine angle type: 48 90°, so it is acute. cos(48) = 0.66913060707025. Write cos(48) in terms of sin. Since 48° is less than 90... We can express this as a cofunction. cos(θ) = sin ...

The cos of 48 degrees is 0.66913, the same as cos of 48 degrees in radians. To obtain 48 degrees in radian multiply 48° by $\pi$ / 180° = 4/15 $\pi$. Cos 48degrees = cos (4/15 × $\pi)$.
