Question 625197
{{{sec(beta)*cot(beta)}}}
When you are not sure how to simplify Trig expressions, try changing the functions into sin's and/or cos's:
{{{(1/cos(beta))*(cos(beta)/sin(beta))}}}
Now we can see that the cos's will cancel:
{{{(1/cross(cos(beta)))*(cross(cos(beta))/sin(beta))}}}
leaving:
{{{1/sin(beta)}}}
which is simply
{{{csc(beta)}}}
