cot2x + csc2x = 2csc2x - 1
1+cosec^2x +cosec^2x
Cot^2x+cosec^x= 1+2 cosec^2x
Would this be correct?
cot2x + csc2x = 2csc2x - 1
1+cosec^2x +cosec^2x
Cot^2x+cosec^x= 1+2 cosec^2x
Would this be correct?

cot2x+csc2x=
cos2x/sin2x + 1/sin2x=
[(1-sin2x)+1]/sin2x
[2-sin2x]/sin2x
2csc2x-1= and done
cos2x/sin2x + 1/sin2x=
[(1-sin2x)+1]/sin2x
[2-sin2x]/sin2x
2csc2x-1= and done
