Answer 1

you have a mistake in 3rd step

Answer 2

Answer:

Step-by-step explanation:

1/1+cos^2 o+1/1+sin^2 o=(1+sin^2 o+1+cos^2 o)/((1+cos^2 o)*(1+sin^2 o))

=(2+sin^2 o+cos^2 o)/(1+sin^2 o+cos^2 o+sin^2 o*cos^2 o)

=(2+1)/(1+1+sin^2 o*cos^2 o)

=3/(2+sin^2 o*cos^2 o)

=(1-sin^2 o*cos^2 o)/(2+sin^2 o*cos^2 o)

Hence,PROVED.......
