For 0<θ<π2\displaystyle {0}<\theta<\frac{\pi}{{2}}, find the values of the trigonometric functions based on the given one

If sec(θ)=82\displaystyle {\sec{{\left(\theta\right)}}}={\frac{{{8}}}{{{2}}}} then
csc(θ)\displaystyle {\csc{{\left(\theta\right)}}}=   ,
` \sin (theta)=   ,
` \cos (theta)=   ,
` tan (theta)=   ,
` \cot (theta)=
