f(x,x)=x f(x,y)=f(y,x) (x+y)f(x,y)=yf(x,x+y)求f(14,52)
f(x,x)=x f(x,y)=f(y,x) (x+y)f(x,y)=yf(x,x+y)求f(14,52)
f(x,x)=x f(x,y)=f(y,x) (x+y)f(x,y)=yf(x,x+y)求f(14,52)
由题知,
f(x,x)=x f(x,y)=f(y,x) (x+y)f(x,y)=yf(x,x+y)
所以,
f(14,52)
=f(14,14+38)
=(52/38)f(14,38)
=(52/38)f(14,14+24)
=(52/38)(38/24)f(14,24)
=(52/24)f(14,14+10)
=(52/24)(24/10)f(14,10)
=(52/10)f(10,14)
=(52/10)f(10,10+4)
=(52/10)(14/4)f(10,4)
=(52/10)(14/4)f(4,10)
=(52/10)(14/4)f(4,4+6)
=(52/10)(14/4)(10/6)f(4,6)
=(52/10)(14/4)(10/6)f(4,4+2)
=(52/10)(14/4)(10/6)(6/2)f(4,2)
=(52/10)(14/4)(10/2)f(2,4)
=(52/2)(14/4)f(2,2+2)
=(52/2)(14/4)(4/2)f(2,2)
=(52/2)(14/4)(4/2)*2
=26*14
=364
f(xy)=f(x)+f(y),证明f(x/y)=f(x)-f(y)
y=f(x),
y=f(f(f(x))) 求导
f(x+y)=f(x)*f(y)说明什么?
f(x+y)=f(x)+f(y)+2xy
二元函数f(x,y)=x+y/x-y,求f(y/x,x/y)
f(x,x)=x f(x,y)=f(y,x) (x+y)f(x,y)=yf(x,x+y)求f(14,52)
已知函数f(x)=3x,求证:f(x)+f(y)=f(x+y)
f(x+y)+f(x-y)=2f(x)cosy,求证f(x)为周期函数
f(x+y)=f(x)*f(y) x>0 f(x)
恒有f(x+y)=f(x)+f(y),若x>0时,f(x)
f(x+y)=f(x)*f(y) x>0 f(x)
函数y=x+f(-x) (x
函数f(x/y)和f(x+y)f(x/y)=f(x)/f(y),f(x+y)=f(x)+f(y)别人说是错的那f(x/y)和f(x+y)应该=什么啊?
f(x+Y)+f(x-y)=2f(x)f(Y) 求其是偶函数 急
求证f（x+y）+f(x-y)=2f(x)f(y)是周期函数
数学题f(X)对一切x y都有f(x+y)=f(x)+f(y)f(X)对一切x y都有f(x+y)=f(x)+f(y)且x>0时,f(x)
已知f(x)=3^x,求证：(1)f(x)·f(y)=f(x+y);(2)f(x)/f(y)=f(x-y).
