If y=- , it is clear t that - b'y' =1. the choices of y and by can v1-p vi- b"- be made in the language of trigonometrical functions as (1) y=cos ec6, by = cot

If y=- , it is clear t that - B'y' =1. The choices of y and By can v1-P VI- B"- be made in the language of trigonometrical functions as (1) y=cos ec6, By = cot v (3) y=cosh0, By= sinh 0 (2) y= sec0, By = tan (4) None of these
