Establish the identity Cos theta Tan theta sin theta Write
     Establish the identity.  Cos theta. Tan theta = sin theta  Write the left side in terms of sine and cosine. Cos theta  Write the result from the previous step as a single fraction.  The fraction from the previous step then simplifies to sin theta using what?  Reciprocal Identity  Even-Odd Identity  Cancellation Property  Pythagorean Identity  Quotient Identity 
  
  Solution
cos@*tan@ = sin@
LHS:
cos@* (sin@ / cos@)
[ cos@ cancel out which gives answer as sin@]
ans will be cancellation property.
