" b) Express "cos^(-1)((cos x)/(1-sin x))-(pi)/(2)cos<(pi)/(2)" in the simplest form "quad (3M)

Express 'tan ^(^^)(-1)((cos x)/(1-sin x)),-pi/2

arctan^(-1)((cos x)/(1-sin x))-cos^(-1)(sqrt((1+cos x)/(1-cos x)))=(pi)/(4),x in(0,(pi)/(2))

The soluation set of inequality (sin x+cos^(-1)x)-(cos x-sin^(-1)x)>=(pi)/(2) is equal to

The value of the expression cos((pi)/(2)-x)cos((3 pi)/(2)+x)-cos(pi-x)cos(2 pi-x)

The value of the expression,E=(cos x)/(1-sin x)+(cos x)/(1+sin x) is
