Answer:

Given:

  • tanA+cotA=2

  • tanA+(1/tanA)=2. (cotA=1/tanA)

  • (tanA)^2 + 1 =2tanA

  • (tanA)^2 - 2tanA + 1 = 0

  • (tanA - 1)^2 = 0.

  • so tanA=1

  • if tanA=1, then cotA=1

  • now according to question;

  • tan^7(A) +cot^7(A)=?

  • (1)^7 + (1)^7=2

  1. hence, tan^7(A) +cot^7(A)=2
