PT costan-1 sincot-1x= root of x2+1/x2+2
4 years ago

cos(tan-1(sin(cot-1x)))=cos(tan-1(sin(sin-1(1/root of 1+x2))))                      cot-1x=tan-1(1/x)=sin-1(1/1+x2)1/2
=cos(tan-1(1/1+x2)1/2)                                            sin(sin-1x)=x
=cos(cos-1(1+x2/2+x2)1/2)                                        tan-1(1/1+x2)=cos-1(1+x2/2+x2)1/2
=(1+x2/2+x2)1/2

=cos(tan-1(1/1+x2)1/2)
=cos(cos-1(1+x2/2+x2)1/2
=(1+x2/2+x2)½

cot-1x=tan-1(1/x)=sin-1(1/1+x2)1/2
sin(sin-1x)=x
tan-1(1/1+x2)=cos-1(1+x2/2+x2)1/2
