Given seccant of thata = 3, use trigonometric identities to find the exact value of
a- Cos thata
b- tan squre of thata
c csc (90 degree - thata)
d- sin squre thata

secTheta=3

but secTheta= 1/cosTheta

solve for cosTheta
Then, sin^2theta+ cos^2Theta=1
solve for sinTheta.
then, Tan theta= sinTheta/cosTheta

you have it.
