Algebra.Com's Answer #268973 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! From sin(theta) = 6/7, we take the inverse sine (call it arcsin) of both sides and get \n" ); document.write( "theta = arcsin (6/7) \n" ); document.write( "Be careful that the angle theta is a second quadrant angle...180 - theta gives it to you... \n" ); document.write( "Once you know cos(theta), which you said you already have, finding the rest is like this... \n" ); document.write( "tan x = sin x / cos x \n" ); document.write( "cot x = cos x / sin x \n" ); document.write( "csc x = 1 / sin x \n" ); document.write( "sec x = 1 /cos x \n" ); document.write( " \n" ); document.write( " |
