Приближенное значение функции в точке 1,05

равно приблизительно 0,8975

Пошаговое объяснение:

y =e^{1 - x^{2} }; x =1,05

Воспользуемся разложением функции f(x) = e^{x} в частный случай ряда Тейлора - ряд Маклорена.

\displaystyle \boxed{ {\mathrm  {e}}^{{x}}=1+{\dfrac  {x}{1!}}+{\dfrac  {x^{2}}{2!}}+{\dfrac  {x^{3}}{3!}}+\cdots =\sum \limits _{{n=0}}^{{\infty }}{\dfrac  {x^{n}}{n!}},x\in {\mathbb  {R}}}

При функции y =e^{1-x^{2} }:

y = e^{1 -x^{2} } \approx 1 + 1 - x^{2}  = 2 - x^{2}

y(1,5) \approx  2 - 1,05^{2} = 2 - 1,1025 =0,8975
