Explain why 51 sin 62 , but 1 15 sin 26 . Because the sine function is not one-to-one we must restrict the domain of the function. The restriction we have chosen to use is , 22     . This becomes the range of the inverse sine function and 5 6 is not in this range. For questions 10 – 13 approximate each expression in radians, with your calculator, accurate to
