Use the given information to find cos(x/2), sin(x/2), and tan(x/2). (Enter your answers in exact form.)
csc x = 7, 0 < x < π/2
sin x=1/cscx=1/7
check:
sinx=1/7
x=8.2132
x/2=4.1066
..
cos(x/2)=cos(4.1066)=0.9974
exact value as computed=≈0.9974
..
sin(x/2)=sin(4.1066)=0.0716
exact value as computed=≈0.0714
..
tan(x/2)=tan(4.1066)=0.0718
exact value as computed=
(let student check computed exact value)
