'cos(3pi2 + x) cos(2pi + x )[ cot(3pi2- x) + cot(2pi + x)] = 1'||

`cot (pi/4 - 2 cot^(-1) 3)` is

tan-1(x)+cot-1(x)=π/2 trigonomery identies solve || tan inverse X + cot inverse X equal pi by 2

Verify the Trigonometric Identity cos(pi/2 + x) = -sin(x)

cos (3 pi/2+ x).cos(2pi +x).((cot 3pi/2 -x) + (cot 2pi + x))= 1

tan^-1(x) + cot^-1(x) = pi/2 | arctan x + arccot x = pi/2
