Question

Найдите первообразную F(x) функции y = f (x), график которой проходит через точку M (a;b):

Answer 1

1) F(x) = x^-1/-1 + C = -1/x + C
-1 = -1/1 + C
C = 0
Ответ: F(x) = -1/x
2) F(x) = x^-2/-2 +C = -1/2x + C
0 = -1/2*(-1) + C
C = -1/2
Ответ:  F(x) = -1/2x -1/2
3) F(x) = 2x - tgx + C
π/2 = 2*π/4 - tgπ/4 + C
π/2 = π/2 - 1 + C
C = 1
Ответ:  F(x) = 2x - tgx + 1
4) F(x) = -2Ctgx + x + C
π/4 = -2*Ctgπ/4 + x + C
π/4 = -2*1 + π/4 + C
C = 2
Ответ:  F(x) = -2Ctgx + x + 2
