Question

cot theta = -1/10. Where theta lies in Quadrant 2. What is csc theta

Answer 1

cot = x/y
csc = r/y

=sqrt(101)/10

Answer 2

r = sqrt(1^2+10^2) = sqrt 101

For proof.

Answer 3

so csc is 101/10?

Answer 4

No, it's sqrt(101) over 10

Answer 5

so (101)^2 over 10

Answer 6

why is it squared

Answer 7

r^2 = x^2+y^2

And sqrt mean square root

Answer 8

means*

Answer 9

oo radical you mean, sorry about that that makesd sense now

Answer 10

Just remember, when you do these kinds of problems, what x, y, and r stand for.

sin = y/r
cos = x/r
tan = y/x
csc = r/y
sec = r/x
cot = x/y

r^2 = x^2+y^2
