LIM(X→2)3X^2-2X+K/X-2 =10 求K "

Lim(x→∞)((2x-3k)/2x)-2x= Lim(x→∞)xsin3/x, LIM(X→2)3X^2-2X+K/X-2 =10 求K 感激不尽!K属于(0,+∞)lim(x→+∞)x^2-k^x/5x^3k+2 lim(x→3)X^2-2X+k/X-3=4,求K的值? lim(x→3)X^2-2X+k/X-3=4,求K的值? lim(x→∞)(1+k/x)^2x=e 求k 设lim［(x-k)/x)］^（-2x）=limxsin2/x,(x→∞）.求k. lim x→∞ （8x^k - 2x+5）/(9x^5+3X^3-2x)=8/9,则K=? lim(x→0) (3x^2-5x+2), lim(x→1)(x^3-3x+2)/(x^3-x^2-x+1) lim (x^3-x^2+4x)/(x^2+x) x→ 0 lim x→∞(2x+1)/(3x-4) lim(x→0)2x^3-x+1 lim(x→1)[(x^(3x-2)-x)sin2(x-1)]/(x-1)^3 lim((√1+x^2)+x)/((√x^3+x)-x)x→+无穷大 当lim┬(x→-2) (x^2-2x+k)/(x+2)=-5时,求k= 求lim(x→0)x cos 1/x lim(x→∞)x^2/ (3x-1)的极限 lim x^2+3x+k/x-2当x趋近于2的时候值为7,求k
