Question

Prove:(tan x + sec x)^2 = 2sec^2 x + 2tan x sec x - 1
I tried it like 3 times

Answer 1

6x

Answer 2

@kirak95197 I am positive that is not correct

Answer 3

Well your wrong

Answer 4

F­uck you

Answer 5

(secx + tanx)^2 = sec^2x + 2 secxtanx + tan^2x

From the right side:
2sec^2x - 1 + 2secxtanx = sec^2x + (sec^2x - 1) = sec^2x + tan^2x + 2 secxtanx

Thus it's proved!
