Algebra.Com's Answer #268732 by Alan3354(69443) You can put this solution on YOUR website! the sin θ = -3/4, tan θ is positive. find the other five functions ( exact values) \n" ); document.write( "----------- \n" ); document.write( "The sine is negative in Quads 3 & 4 \n" ); document.write( "The tan is positive in Quads 1 & 3 \n" ); document.write( "--> the angle is in Quad 3 \n" ); document.write( "----------------- \n" ); document.write( "The hypotenuse = 4, x = -3, y = - sqrt(7) \n" ); document.write( "cos = -3/-sqrt(7) = 3sqrt(7)/7 \n" ); document.write( "tan = sin/cos = (-3/4)/(3sqrt(7)/7 = -3sqrt(7)/-21 = sqrt(7)/7 \n" ); document.write( "------------- \n" ); document.write( "You can do the remaining 3 \n" ); document.write( "cot = 1/tan \n" ); document.write( "sec = 1/cos \n" ); document.write( "csc = 1/sin \n" ); document.write( " |
