tan(45)=1/x??

6. anonymous

(r)sin(3π/4)

|dw:1441248786396:dw| $\tan \left( \frac{ 3 \pi }{ 4 } \right)= - 1$ we know the tan ratio is $\tan \theta = \frac{ y }{ x }$

8. anonymous

1/x

9. anonymous

$\frac{ y }{ x } = -1$

10. anonymous

so -1

11. anonymous

Bingo

12. anonymous

what would the point be? just -1 or a point

13. anonymous

No our point is then (-1,1)

14. anonymous

Since x = -1, and y = 1

15. anonymous

okay, thank you

Yw :)
