Calculate sin(63) sin is found using Opposite/Hypotenuse. Determine quadrant: Since 0 ≤ 63 ≤ 90 degrees it is in Quadrant I. sin, cos and tan are positive. Determine angle type: 63 90°, so it is acute. sin(63) = 0.89100652361796. Write sin(63) in terms of cos. Since 63° is less than 90... We can express this as a cofunction. sin(θ) = cos ...
