Answer 3

im here

Answer 4

@waterineyes are you there?

Answer 5

Firstly here, subtract tan(x) from both the sides..

Answer 6

are you sure? i think youre supposed to divide tan(x) from both sides

Answer 7

You can only divide tan(x) if it is not equal to 0.. We must consider tan(x) = 0 case too..

Answer 8

Proceed by subtracting tan(x) from both the sides and then taking tan(x) common from both the terms in LHS..
