Algebra.Com's Answer #580798 by Alan3354(69443) You can put this solution on YOUR website! Very similar to this one: \n" ); document.write( "=================== \n" ); document.write( "If tan theta=3/2 and cos theta<0, find the other five trig functions of theta \n" ); document.write( " ---------- \n" ); document.write( " tan = y/x = 3/2 \n" ); document.write( "r = sqrt(y^2 + x^2) = sqrt(13) \n" ); document.write( " ----- \n" ); document.write( " tan + and cos < 0 --> Q3 \n" ); document.write( " --- \n" ); document.write( " sin = y/r = 3/sqrt(13) --> -3sqrt(13)/13 \n" ); document.write( " cos = x/r = 2sqrt(13)/13 \n" ); document.write( " cot = 1/tan \n" ); document.write( " sec = 1/cos \n" ); document.write( " csc = 1/sin \n" ); document.write( " |
