You can put this solution on YOUR website!
simplify the given ratios , for example :
\n" ); document.write( "(1+tan^2A) = sec^2A
\n" ); document.write( "Note: A simpler form always depends on the observer.
\n" ); document.write( "Your equation is true because it is one of the Pythagorean
\n" ); document.write( "relations for trig functions.
\n" ); document.write( "---
\n" ); document.write( "It might be \"simplified\" as follows:
\n" ); document.write( "Multiply thru by cos^2(A) and you get:
\n" ); document.write( "cos^2(A) + sin^2(A) = 1
\n" ); document.write( "Note: This also is a Pythagorean relation for trig functions.
\n" ); document.write( "----
\n" ); document.write( "Is it simpler? That depends on what you know about trig relations.
\n" ); document.write( "-----
\n" ); document.write( "It simplifies further to 1 = 1
\n" ); document.write( "---
\n" ); document.write( "That definately is \"simpler\".
