image link doesn't work. some you got correct.
noted that is in quad III ...
using the identity ...
Given: cot theta = sqrt2/4 , pi < theta < 3pi/2
find the exact value of the other five trig functions of theta, leave answers in radical form.
could someone show me how to do this, when i did it i got:
sin theta= -2sqrt2/3
cos theta= -1/3
tan theta= 2/sqrt2
cot theta= sqrt2/4
sec theta= -3
csc theta= -3sqrt2/4
is this correct?
a friend in class said that it wasn't and that i had to start by doing cot theta= cos/sin cos = sqrt2 sin = 4....
Here's another approach . . .
Find the exact value of the other five trig functions of .
We are given: .
That is, is in a right triangle with: .
Pythagorus says: .
Since is in Quadrant 3, only and are positive.
