Algebra.Com's Answer #526232 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! find the values of the trigonometric functions of theta from the information given. Sec theta =9, sin theta 《 0. \n" ); document.write( "----------------------- \n" ); document.write( "If sec is positive and sin is negative, theta is in QIV \n" ); document.write( "where x is positive and y is negative. \n" ); document.write( "------------------------------- \n" ); document.write( "Since sec(t) = 9/1 = r/x, r = 9 and x = 1 \n" ); document.write( "Then y = -sqrt[9^2-1] = -sqrt(80) = -4sqrt(5) \n" ); document.write( "-------------------------------------------------- \n" ); document.write( "a)sin theta = y/r = -4sqrt(5)/9 \n" ); document.write( "b)cos theta = 1/sec = 1/9 \n" ); document.write( "c)csc theta = y/x = -4sqrt(5) \n" ); document.write( "d)sec theta = 9 \n" ); document.write( "e)cot theta = x/y = -1/4sqrt(5)\r \n" ); document.write( "\n" ); document.write( "================================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "================================ \n" ); document.write( " \n" ); document.write( " |
