Algebra.Com's Answer #273402 by richard1234(7193)![]() ![]() You can put this solution on YOUR website! By the Pythagorean identity, sin (theta) = +- 4/5, but since it is less than zero, sin (theta) = -4/5. To find the rest, just use the following definitions:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "sec x = 1/cos(x) \n" ); document.write( "csc x = 1/sin(x) \n" ); document.write( "tan x = sin(x)/cos(x) \n" ); document.write( "cot x = 1/tan(x) = cos(x)/sin(x) \n" ); document.write( " |
