Question 887259
If sin a = √7/4 and a is in Quadrant II, find the value of the other five trigonometric functions.
Reference angle a is in quadrant II in which sin>0, cos<0, tan<0
cos a=-&#8730;(1-sin^2 a)=-&#8730;(1-7/16)=-&#8730;(9/16)=-3/4
tan a=-&#8730;7/3
csc a=4/&#8730;7=4&#8730;7/7
sec a=-4/3
cot a=-3/&#8730;7=-3&#8730;7/7
