Prove the identity.
tan^5x = tan x (sec² x - 2 sec² x + 1)

Prove The Identity Tan5x Tan X Sec X 2 Sec X 1 class=

Sagot :

bunnuika

goal:tan^5x=tanx(sec²x-2sec²x+1)

proof: from l.h.s to r.h.s

tan^5x=(tanx)^5=((tanx)(tan²x)(tan²x))

from trigonometry identity

(tan²x)=sec²x-1

tan^5x=(tanx(sec²x-1)(sec²x-1))

=(tanx(sec^4x-sec²x-sec²x+1))

=(tanx(sec^4x-2sec²x+1))
