Question

If sin(theta) = - 15/17 ..... what is cos(theta), tan(theta), csc(theta), sec(theta) and cot(theta) ?

Answer 1

cot(theta) sin(theta) = - 15/17
cos^2(theta), =1-sin^2(theta)
=1-(15/17)
=1-225/289
289-225/289
=64/289
=8/17

sec(theta) =inverse of cos=17/8
tan(theta)=sin(theta) /cos(theta),
-15/17 divided by 8/17
=-15/8
cot(thta)=-8/15
