Since $pi$ equals 3.14, 0.942 would be $pi/10$ . Therefore, if $cot (pi/10)$ is given, all trignometrical ratios can be determined.

$Sin (pi/10) = 1/sqrt(1+cot^2 (pi/10)$
$cos (pi/10)= sqrt (1- sin^2 (pi/10)$

$tan(pi/10)= 1/cot(pi/10)$

$csc(pi/10)= sqrt(1+cot^2 (pi/10)$

$sec(pi/10)= 1/cos (pi/10)$
