if sec Q = 5/4 verify that tanQ/1+tanA sin Q/A

construct a right-angled triangle using the fact that
secQ = 5/4
then secQ = 4/5
adjacent to Q is 4, hypotenuse is 5 ,then
opposite^2 + 16 = 25
opposite = 3
(ahhh, the 3,4,5 right-angled triangle)
so taně = 3/4, sinQ = 3/5
The expression I am to verify makes no sense, but after you fix it, the above information will let you determine it.
