Find the exact values of the other trig functions of theta given sec theta=7 and sin theta is less than 0.

If sec Ø = 7
then cosØ = 1/7
Also since sinØ < 0, then Ø must be an angle in quadrant IV
From the righttriangle drawn in standard position, the missing side would be √48 or 4√3
sinØ = 4√3/7
cscØ = 7/(4√3)
cosØ = 1/7
secØ = 7 , (that was given)
tanØ = 1/(4√3)
cotØ = 4√3
