Question 1084477
If {{{sin(theta) = -2/7}}}, what are the possible coordinates for point "P?" What are the values of {{{cos(theta)}}} and {{{tan(theta)}}}?
-----------
cos = sqrt(1 - sin^2) = sqrt(45/49) = 3sqrt(5)/7
cos may be + or minus, the quadrant is not given
tan = sin/cos = -2/(3sqrt(5)) = -2sqrt(5)/15 (sign not known)
==============
Where is point P?
