Answer 1

$\huge\mathbb\red{Heya!!!}$✌️

HeRe uhh Gø_______☺️

Solution:-

Cos4x = Cos2x

Cos∅ = CosA

∅ = 2nπ ± A

4x = 2nπ ± 2x

________________________________

On taking +ve sign

4x = 2nπ + 2x

2x = 2nπ

x = nπ

________________________________

On taking -ve sign

4x = 2nπ - 2x

6x = 2nπ

x = 2nπ/6

x = nπ/3
