Question

Given that tanA= (squareroot 7)/4 and angle A is in quadrant 3. find cscA?

Answer 1

Tangent is sin/cos

so that makes sin = sqrt 7

csc is 1/sin

so 1/sqrt 7 is csc

but this must be rationalized properly into sqrt 7 /7

Answer 2

okay!

Answer 3

would the final answer be \[\sqrt{23} / 7\]

Answer 4

no, it is sqrt 7 /7
