QJEEM22Maf7d0: JEE Main 2022 Mathematics - Class 11 JEEM22Maf7d0 Solution: The number of solutions of

Period of $$|\cos x|=\pi$$

And period of $$\sin x=2\pi$$

Graph of $$\sin x$$ and $$|\cos x|$$ cuts each other at two points A and B in $$\left[0,2\pi \right]$$

So, in $$\left[-4\pi ,4\pi \right]$$, total 4 similar graph will be present and graph of $$\sin x$$ and $$|\cos x|$$ will cut $$4\times 2=8$$ times.

$$\therefore$$ Total possible solutions = 8.
