Question

if sin x + cos x is equal to 2 then find tan x + sin x + x​

Answer 1

Hey Mate !!

Your Solution with explanation is here :-

Sin X + Cos X = 2 ..........(given)

Sin X = 2–Cos X ________(1)

we have to find tan X + Sin X = ?

We also know that tan X = Sinx / cos X

So, SinX/cos X + Sinx

= Sinx (Cos X+1)

Put the value of X from eqn 1.

=1- cos X (Cos X+1)

=1- Cos²X - Cos X
