Summani xisoblang


$$y = \frac{ln(a^{2 \sin{x}}) + e^{2x}}{arctan(x) + b} + c$$

$$-\pi \le x \le \pi , h = \frac{\pi}{10}$$
Bu yerda $x$ – $-\pi$ va $\pi$ oralig’ida, $h$ sikl qadami


Kiruvchi ma’lumotlar:

$a,b,c$ butun son $(0 \le a,b,c \le 100)$;


Chiquvchi ma’lumotlar:

$y$ – lar summasini $10^{-2}$ aniqlikda chiqarilsin.
