SSSSS [86.1K]

Step-by-step explanation:

tan2x = sin2x/cos2x

we know that ,

  • sin2x = 2sinxcosx
  • sin2x = 2sinxcosx cos2x = cos²x - sin²x

Since, tan2x = 2sinx*cosx/cos²x- sin²x

Dividing by cos²x in numerator and denominator.

We get ,

  • tan2x = 2sinx/cosx / 1- sin²x/cos²x

  • Since, we get tan2x= 2tanx/1-tan²x

  • Option (c) is correct option.
