TRIGONOMETRIC FUNCTIONS - EXERCISE 1

Find the period of the function tex2html_wrap_inline142 .

Solution: For the function tex2html_wrap_inline142 to run through a full cycle, the angle tex2html_wrap_inline146 should run from tex2html_wrap_inline148 to tex2html_wrap_inline150 , and hence t should run from t=0 to t=2/7. The period of f(t) is then 2/7.
