Some less able students are not at ease when working with Irrational Numbers. Overall, though, the advantages far outweigh that prejudice/disadvantage.
One radian is equal to roughly 57 degrees!
Degree measure is based off of a division of 360 degrees in a circle. Radian measure is based off of a division of 2PI in a full circle.
