Calculate cos(74) cos is found using Adjacent/Hypotenuse. Determine quadrant: Since 0 ≤ 74 ≤ 90 degrees it is in Quadrant I. sin, cos and tan are positive. Determine angle type: 74 90°, so it is acute. cos(74) = 0.27563735723563. Write cos(74) in terms of sin. Since 74° is less than 90... We can express this as a cofunction. cos(θ) = sin ...
