    ∵在△EFP中,|EF|=2c,EF上的高為點(diǎn)P的縱坐標(biāo),∴S△EFP=4/3c2=12,∴c=3,即P點(diǎn)坐標(biāo)為(5,4).由兩點(diǎn)間的距離公式|PE|=√("(" 5+3")" ^2+4^2 )=4√5,|PF|=√("(" 5"-" 3")" ^2+4^2 )=2√5,∴a=√5.又b2=c2-a2=4,故所求雙曲線的方程為x^2/5-y^2/4=1.5.求適合下列條件的雙曲線的標(biāo)準(zhǔn)方程.(1)兩個(gè)焦點(diǎn)的坐標(biāo)分別是(-5,0),(5,0),雙曲線上的點(diǎn)與兩焦點(diǎn)的距離之差的絕對(duì)值等于8;(2)以橢圓x^2/8+y^2/5=1長軸的端點(diǎn)為焦點(diǎn),且經(jīng)過點(diǎn)(3,√10);(3)a=b,經(jīng)過點(diǎn)(3,-1).解:(1)由雙曲線的定義知,2a=8,所以a=4,又知焦點(diǎn)在x軸上,且c=5,所以b2=c2-a2=25-16=9,所以雙曲線的標(biāo)準(zhǔn)方程為x^2/16-y^2/9=1.(2)由題意得,雙曲線的焦點(diǎn)在x軸上,且c=2√2.設(shè)雙曲線的標(biāo)準(zhǔn)方程為x^2/a^2 -y^2/b^2 =1(a>0,b>0),則有a2+b2=c2=8,9/a^2 -10/b^2 =1,解得a2=3,b2=5.故所求雙曲線的標(biāo)準(zhǔn)方程為x^2/3-y^2/5=1.(3)當(dāng)焦點(diǎn)在x軸上時(shí),可設(shè)雙曲線方程為x2-y2=a2,將點(diǎn)(3,-1)代入,得32-(-1)2=a2,所以a2=b2=8.因此,所求的雙曲線的標(biāo)準(zhǔn)方程為x^2/8-y^2/8=1.當(dāng)焦點(diǎn)在y軸上時(shí),可設(shè)雙曲線方程為y2-x2=a2,將點(diǎn)(3,-1)代入,得(-1)2-32=a2,a2=-8,不可能,所以焦點(diǎn)不可能在y軸上.綜上,所求雙曲線的標(biāo)準(zhǔn)方程為x^2/8-y^2/8=1.
