Do questions b, c and e and show all your work (all of it)

Those are too many questions because each answer is very long.

I will do b for you and that should help you to figure out how to do the others.

b) 1 - cos(2x)
    = tan(x)
         sin(2x)

1 - [cos^2 (x) - sin^2 (x) ]
= tan(x)
         2 cos(x)(sin(x)

1 - cos^2(x) + sin^2(x)
= tan(x)
        2cos(x)sin(x)

[1 - cos^2(x) ] + sin^2(x)
= tan(x)
     2cos(x)sin(x)

sin^2(x) + sin^2 (x)
=  tan(x)
   2cos(x)(sin(x)

   2 sin^2 (x)
= tan(x)
2 cos(x)sin(x)

 sin(x)
= tan(x)
 cos(x)

tan(x) = tan(x)

Ais the correct answer - trinomial (three parts) degree of 2 (highest exponent being 2)hope this , and mark brainliest!
