Составьте алгоритм и программу в basic вычисления значений функции на произвольном отрезке с произвольным шагом: y = 1 / x2 + 1 - при -1 < = x < = 1; y = x3 - 5 - в остальных случаях.
DIM x AS DOUBLE, a AS DOUBLE, b AS DOUBLE, h AS DOUBLE CLS INPUT "a=", a INPUT "b=", b INPUT "h=", h FOR x = a TO b + h / 2 STEP h IF ABS(x) <= 1 THEN y = 1 / x * x + 1 ELSE y = x ^ 3 - 5 END IF PRINT x, y NEXT x
