Question 717680
{{{csc(theta)*tan(theta)*cos(theta)}}}
In Trig, a good rule of thumb is: "When you can't see anything better to do, try rewriting sec's, csc's, tan's and cot's in terms of sin's and/or cos's and if it gets easier." Let's try this:
{{{(1/sin(theta))*(sin(theta)/cos(theta))*cos(theta)}}}
As we can see, <i>everything</i> cancels out! So the answer is 1.
