Algebra.Com's Answer #339043 by lwsshak3(11628)![]() ![]() ![]() You can put this solution on YOUR website! if cos^-1(-2/7)=x, find the exact value for each: sinx,cosx, tanx, cotx, secx,& cscx? \n" ); document.write( "** \n" ); document.write( "cos^-1(-2/7) is an inverse cos function which says cos of angle x=-2/7, which means you are working with a reference angle x in quadrant II where cos is negative. \n" ); document.write( "sin x=√45/7 \n" ); document.write( "cos x=-2/7 (given) \n" ); document.write( "tan x=-√45/2 \n" ); document.write( "csc x=7√45/45 \n" ); document.write( "sec x=-7/2 \n" ); document.write( "cot x=-2√45/45 \n" ); document.write( " |
