f(x)=log_{3}(sinsqrt{x})xcos(e^3x+1 সমাধান কৰক

$$f ( x ) = \log _ { 3 } ( \sin \sqrt { x } ) x \cos ( e ^ { 3 x + 1 }$$

f-ৰ বাবে সমাধান কৰক

$$f=\log_{3}\left(\sin(\sqrt{x})\right)\cos(e^{3x+1})$$

$$\exists n_{1}\in \mathrm{Z}\text{ : }\left(x>4\left(\pi n_{1}\right)^{2}\text{ and }x<\left(2\pi n_{1}+\pi \right)^{2}\right)$$

$$n_{1}>-1\text{ and }not(n_{1}<0)\text{ or }\left(x>0\text{ and }x<\pi ^{2}\right)$$
