Algebra.Com's Answer #380243 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! sec theta/tan theta + (1 - tan theta)/sec theta = (1+tan theta)/(sec theta)(tan theta) \n" ); document.write( "------------- \n" ); document.write( "sec/tan + (1 - tan)/sec = (1 + tan)/(sec*tan) (I'll assume the last den is sec*tan) \n" ); document.write( "----------- \n" ); document.write( "Multiply thru by sec \n" ); document.write( "sec^2/tan + 1 - tan = (1 + tan)/tan = cot + 1 \n" ); document.write( "sec^2/tan + 1 - tan = cot + 1 \n" ); document.write( "Multiply by tan \n" ); document.write( "sec^2 + tan = 1 + tan \n" ); document.write( "Not an identity. \n" ); document.write( "==================== \n" ); document.write( "You need to make it clear, add parentheses to eliminate guessing at what the terms are. \n" ); document.write( " \n" ); document.write( " |
