19. (90-8 - 00 ) Ushbu \( f(x)=\frac{3}{4 \sqrt{16}} \) funksiyaniag bosh- lang ich funksiyasini toping. \( \begin{array}{lll}\text { A) } \frac{3}{2} \sqrt{x}+C & \text { B) } 3 \sqrt{x}+C & \text { C) } \frac{4}{3} \sqrt{x}+C \\ \text { D) }-\frac{3}{2} \sqrt{x}+C & \text { E) } 6 \sqrt{x}+C & \end{array} \)

\( f ( x ) = \int e ^ { 58379 } d x \)

Check whether the differential equation: Is Exact or not? If yes, \( \frac{\text { find }}{\left(6 x^{2}+4 x y+y^{2}\right) d x+\left(2 x^{2}+2 x y-3 y^{2}\right) d y=0} \).

Find the value of integration for the following function أوجد قيمة التكامل للدالة التالية: \( f(x)=\int\left(e^{x}+3 x^{2}+2 x\right) d x \)

2. Calcolare l'integrale della funzione \( f(x, y)=x+2 y \) sul settore circolare \[ S=\left\{(x, y):(x+1)^{2}+y^{2} \leq 2, y \leq 0, y \leq-x-1\right\} \]
