Use the fundamental identities to find all of the trigonometric ratios if the variable satisfies the given conditions.
\n" ); document.write( "a) sin x=12/13 and cos x<0
\n" ); document.write( "cos^2 = 1 - sin^2
\n" ); document.write( "cos^2 = 1 - 144/169 = 25/169
\n" ); document.write( "cos = 5/13
\n" ); document.write( "x = arccos(5/13) = arccos(-5/13)
\n" ); document.write( "x = ~ -67.38º
\n" ); document.write( "------------------
\n" ); document.write( "b)cos x =-4/3 , sinx>0
\n" ); document.write( "c)tan x = -24/7 , sinx>0
\n" ); document.write( "d)tan x = 4/3 , sinx>0
\n" ); document.write( "e)cot x= 4 , sinx>0
\n" ); document.write( "f)cos x=3/5
\n" ); document.write( " \n" ); document.write( "
