You can put this solution on YOUR website! Use fundamental identities to find the values of the trigonometric functions (as decimal values within .001) for the given conditions.
cos(t) = 0.31
sin(t) > 0

Given data shows reference angle is in quadrant I where both sin and cos>0
sin(t)=√(1-cos^2(t))=√(1-.31^2)=√(1-.096)=√.904=0.951
csc(t)=1/sin(t)=1/.951=1.052
cos(t) = 0.31
sec(t)=1/cos(t)=1/.31)=3.226
tan(t)=sin(t)/cos(t)=.951/.31=3.068
cot(t)=1/tan(t)=1/3.068=0.326
