De esta manera / Thereby f = ف (a, b, c).
Propiedades que esta función tendrá: / Properties of this function:
- Proporcionalidad: / proportionality:
ف (a, b, c) = ف (pa, pb, pc). " p.
- Definición de circunferencias: / Definition of the circumferences:
ف (x, y, r) = 2; ف (x-x0, y-y0, r) = 2.
- Definición de rombo: / Definition of the rhombus:
ف (|x|, |y|, r) = 1.
- Definición de cuadrados: / Definition of the squares:
ف (x, y, r) → ∞
- Definición de oblongos:
ف (x, y, r) = n
ف (x, y, r) = n
ف (x, y, r) = 4 |
- Derivadas: / Derivatives:
y = ف (x, b, c).
dy/dx = 1/{ x [(ln (ف(x) ) /ف(x)2 ) + ( ln(c)c ﻑ(x) – ln(b)b ﻑ(x) )]}.
Demostración: / Demostration:
xy + by = cy. → x = ( cy – by ) 1/y. →
dx/dy = ( cy – by ) 1/y(ln (1/y ) )(-1/y2 ) + ( cy – by ) 1/y( ln(c)cy – ln(b)by )
dx/dy = x [(ln (y ) /y2 ) + ( ln(c)cy – ln(b)by )]
dx/dy = x [(ln (ف(x) ) /ف(x)2 ) + ( ln(c)c ﻑ(x) – ln(b)b ﻑ(x) )]
dy/dx = 1/{ x [(ln (ف(x) ) /ف(x)2 ) + ( ln(c)c ﻑ(x) – ln(b)b ﻑ(x) )]}.
dy/dx = 1/{ x [(ln (ف(x) ) /ف(x)2 ) + ( ln(c)c ﻑ(x) – ln(a)a ﻑ(x) )]}.
y = ف (a, b, x).
dy/dx = 1/{ x [(ln (ف(x) ) /ف(x)2 ) + ( ln(a)a ﻑ(x) + ln(b)b ﻑ(x) )]}.
- Inversa:
y = ف (x, b, c). → x = ( cy – by ) 1/y
y = ف (a, x, c). → x = ( cy – ay ) 1/y
y = ف (a, b, x). → x = ( ay – by ) 1/y
ف (a, b, c) = ف (b, a, c)
