Answer:

  • cotx - cot2ⁿx

Step-by-step explanation:

  • <em>Note: finding the sum not x</em>

<u>First rewrite the first term as:</u>

  • 1/sin2x =
  • sinx / (sinxsin2x)  =
  • sin(2x-x) / (sinxsin2x)  =
  • (sin2xcosx - cosxsinx) / (sinxsin2x) =
  • (sin2xcosx)/(sinxsin2x) - (cos2xsinx)/(sinxsin2x) =
  • cosx/sinx - cos2x/sin2x =
  • cotx - cot2x

<u>Now the sum is:</u>

  • S = cotx - cot2x + cot2x - cot4x +... + cot2ⁿ⁻²x - cot2ⁿx =
  • cotx - cot2ⁿx
