Summani xisoblang


$$y = \sqrt[5]{\frac{ax + b}{b^2 + cos^2 x}} - \frac{\sin{x^2}}{ab}$$

$$d \le x \le c , h = 1.5 $$
Bu yerda $x$ – $d$ va $c$ oralig’ida, $h$ sikl qadami


Kiruvchi ma’lumotlar:

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


Chiquvchi ma’lumotlar:

$y$ – masala yechimi $10^{-2}$ aniqlikda chiqarilsin.
