Hi aspirant,
Since you have not given any limits for integration I will consider it to be a question from indefinite integral. In the question we have to integrate the given function with respect to X. Therefore the required integral
== 2x+ 2Cosx/2 -Sinx
Here we used the basic formula of trigonometric integration which you must know for solving the equation.
Hope it helps!
Question : If $\cos x+\sin x=\sqrt{2} \cos x$, what is the value of $(\cos x-\sin x)^2+(\cos x+\sin x)^2$?
Option 1: $2$
Option 2: $1$
Option 3: $0$
Option 4: $\frac{1}{\sqrt{2}}$
