Question

Check my answer trig function values

Find the remaining five trigonometric function values
Sec θ =-8 and θ is in the second quadrant

sin θ= radical 63/8
cos θ = -1/8
tan θ = -radical 63
cot θ = -radical 63/radical63
csc θ = 8radical63/63

Answer 1

find the other side via pythagoras, then you can find all ratios

Answer 2

isnt the hypotenuse 8?

Answer 3

x is -1?

Answer 4

first one is right
second one is right

Answer 5

yeah i just labelled it as a length
you are in quadrant 2 so cosine is negative and sine is positive etc

Answer 6

third one is right

Answer 7

cotangent is wrong

Answer 8

reciprocal of tangent, should be \(-\frac{1}{\sqrt{63}}\)

Answer 9

cosecant is right

Answer 10

but you can't have radical in the denominator

Answer 11

oh ok

Answer 12

then it is
\[-\frac{\sqrt{63}}{63}\]

Answer 13

k ty
