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.
