Question

Let θ = 135°. Find the exact values of tan θ , cos θ & csc θ

Answer 1

they want youto use the angle addition formulas

Answer 2

but its really just 45 degrees

Answer 3

-cos; and sin

Answer 4

tan 135=-1
cos 135=-0.707
csc 135=1.414

Answer 5

sin(45) = 1/sqrt(2); csc(45) = sqrt(2)

-cos(45) = -sqrt(2)/2

-tan(45) = -1

Answer 6

decimals are 'exact' values; gotta keep the sqrts

Answer 7

sin(135)=sin(180-45)=cos(180)sin(45)-cos(45)sin(180)
cos(135)=sin(180-45)=cos(180)cos(45)+sin(180)sin(45)
use this

Answer 8

decimals ARENT exact.... my keyboard hates me

Answer 9
