What Fraction Is Cos 90? [Solved]
Usually, the degrees are represented in the form of 0°, 30°, 45°, 60°, 90°, 180°, 270° and 360°. Here, let us discuss the value for cos 90 degrees which is equal to zero and how the values are derived using the quadrants of a unit circle. Value of Cos 90° = 0.
show that cos90=0, tan 90=undefined and sin90=1?
This video shows the proof of why
