What are the sine, cosine, and tangent of 5 pi over 4 radians?

[tex]sin( \frac{5 \pi }{4}) = 0.07 [/tex] rounded to two decimal places 

If you have a scientific calculator, you can work this out by first change the setting from degree to radian

[tex]cos( \frac{5 \pi }{4}) = 0.998 [/tex] rounded to three decimal places

[tex]tan( \frac{5 \pi }{4}) = 0.069 [/tex] rounded to three decimal places
