what are the trig function values of cot x= -8/15 and 3 pie/2 greater than or equal to x greater than or equal to 2 pie
\n" ); document.write( "***
\n" ); document.write( "Given: cot x=-8/15 (3π/2 ≥ x ≥ 2π)
\n" ); document.write( "I think you meant the interval to be(3π/2 ≤ x ≤ 2π) which is quadrant IV in which sin<0, cos>0, tan<0
\n" ); document.write( "Hypotenuse of reference right triangle in quadrant IV=√(8^2+15^2)=√(64+225)=√289=17
\n" ); document.write( "cot x=-8/15
\n" ); document.write( "tan x=-15/8
\n" ); document.write( "sin x=-15/17
\n" ); document.write( "cos x=8/17
\n" ); document.write( "csc x=-17/15
\n" ); document.write( "sec x=17/8 \n" ); document.write( "
