Question

find the exact value of the trigonometric function at the given real number.If the value is undefined, enter no solution.

sin17(pie)
cos19(pie)/2
tan13(pie)/2

Answer 1

good god

Answer 2

first of all sine is defined for all real numbes, so it cannot be undefined

Answer 3

second of all the symbol
\[\pi\] is a greek letter,
if you want to write it in english it is called "pi" not "pie"

Answer 4

sin 17pi = sin pi = 0
i think!!!

Answer 5

if you want to find the value of
\[\sin(17\pi)\] you can say that since sine is periodic with period
\[2\pi\] then
\[\sin(17\pi)=\sin (\pi)=0\]

Answer 6

ah
