Simplify the following as a product of trigonometric functions with no powers. Write the functions in alphabetical order by function abbreviation, and use the multiplication sign between the functions. Alphabetical order means using the function abbreviations. So, the alphabetical order for our 6 trigonometric functions is: cos(x), cot(x), csc(x), sec(x), sin(x), tan(x). 1 1+ sin(x) 1 1-sin(x) Submit Question

Use periodicity to first rewrite each expression as the same trigonometric function of an angle in [-T, π). Then use that angle to determine the exact value from the unit circle. If undefined, write DNE. sec(-25) = sec( csc (¹7) = csc ( sin(- 17 ) = sin([])=[ sec (³) = sec ( Use periodicity to first rewrite each expression as the same trigonometric function of an angle in [0, π). Then use that angle to determine the exact value from the unit circle. If undefined, write DNE. cot (37) = cot( tan (9) =tan(| =

Reduce the following expression to a single trigonometric function: sec2 (x) tan(x) tan(x)
