Algebra.Com's Answer #277308 by stanbon(75887) ![]() You can put this solution on YOUR website! In which quadrant will theta lie if sin>0 and cos<0? \n" ); document.write( "--- \n" ); document.write( "sin is positive in I and II \n" ); document.write( "cos is negative in II and III \n" ); document.write( "---- \n" ); document.write( "Both conditions are met in Quadrant II \n" ); document.write( "---------------------------------------------- \n" ); document.write( "2) Find sin(theta) if the terminal side of theta lies along the line of y=-2x in quadrant 2? \n" ); document.write( "Let x = -1, then y = 2 \n" ); document.write( "--- \n" ); document.write( "Then r = sqrt[1^2+2^2] = sqrt(5) \n" ); document.write( "--- \n" ); document.write( "The sin(theta) = y/r = 2/sqrt(5) \n" ); document.write( "---------------------------------------------- \n" ); document.write( "3)If cot(theta)= 50 what would tan(theta) be? \n" ); document.write( "tan(theta) = 1/[cot(theta)] = 1/50 = 0.02 \n" ); document.write( "============================================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
