  In some situations, it would be a lot easier to express angles in radians.
  
  And in fact, the SI unit for angle is in fact the radian:

  Oh no.
  
  Does that mean you did everything correctly but the answers were all wrong because your calculator was feeling rad and you only realized it at the end of the examination??

  u should know when your answers are much too small...., i.e. mostly less than 10...
  
  Degrees are usually much larger...
