Algebra.Com's Answer #209461 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! find the exact value of six trig functions of pi/4 radians. \n" ); document.write( "Draw a 45/45/90 right triangle \n" ); document.write( "Let the hypotenuse be 1. \n" ); document.write( "Then, using Pytagoras, each side is sqrt(2) \n" ); document.write( "---- \n" ); document.write( "sin (pi/4) = 1/sqrt(2) \n" ); document.write( "csc pi/4 = sqrt(2)/1 = sqrt(2) \n" ); document.write( "-------------------------------- \n" ); document.write( "cos (pi/4) = 1/sqrt(2) \n" ); document.write( "sec (pi/4) = sqrt(2) \n" ); document.write( "-------------------------------- \n" ); document.write( "tan (pi/4)= sqrt(2)/sqrt(2) = 1 \n" ); document.write( "cot (pi/4)= sqrt(2)/sqrt(2) = 1 \n" ); document.write( "============================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "============================== \n" ); document.write( " \n" ); document.write( " |
