∴a b≥2√ab 1/(a b)≤1/2√ab.仿照y=a^(2x-2),(a>0≠1)仿照2 3b2≥λb(a b)1/2×2/3×3/4×4/5×…×98/99×99/100

说说f(x)=(x方 ax-2)/(x方-x 1)x^2/a^2 y^2/b^2=1中,SPF1F2=b^2*tanβ/
在线等f(x)=(x方 ax-2)/(x方-x 1)x^2/a^2 y^2/b^2=1中,SPF1F2=b^2*tanβ
请问一下f(x)=(x方 ax-2)/(x方-x 1)x^2/a^2 y^2/b^2=1中,SPF1F2=b^2*tan
想知道：f(x)=(x方 ax-2)/(x方-x 1)x^2/a^2 y^2/b^2=1中,SPF1F2=b^2*tan
说说y=log0.5(2x2-3x 1)x^2/a^2 y^2/b^2=1中,SPF1F2=b^2*tanβ/2
说说y=log0.5(2x2-3x 1)x^2/a^2 y^2/b^2=1中,SPF1F2=b^2*tanβ/2
在线等y=log0.5(2x2-3x 1)x^2/a^2 y^2/b^2=1中,SPF1F2=b^2*tanβ/2
