lim(cos(sqrt(x)))^1/x

lim(cos(sqrt(x)))^1/x lim{sqrt[2(1-cos(x)]}/x 在x趋于0处的极限是多少是怎样求到的? lim x->正无穷大 x ( sqrt(x^2+1)-x ) lim x->0(sqrt(sin(1/x^2)) 求极限 lim sqrt(1+tanx)-sqrt(1+sinx)/(x*sqrt(1+(sinx)^2)-x) x趋近于0 lim (sqrt(x+2)-sqrt(x))/(sqrt(x+1)-sqrt(x)) (X趋近于正无穷)答案是2。。。步骤详细点，谢谢 1-sqrt(3)=2cos²x+sqrt(3)sin2x则x等于多少 (sqrt(cos(x))*cos(200x)+sqrt(abs(x))-0.7)*(4-x*x)^0.01,sqrt(9-x^2),-sqrt(9 lim(x->0)∫sin(sqrt(t))dt/x^a, 求两道极限计算题：1）lim(x->1):(x^n-1)/(x-1) (n属于自然数集,x^n表示x的n次方)2）lim(x->0+0): sqrt(x-x^2) (sqrt()表示根号下) 高数题 lim(x-无穷大) x cos 1/x lim(x~无穷大) Xcos 1/X lim(x→0)(1/x)*cos(1/x) lim x趋向0 (1+cos^2(1/x))^x lim(sin(x^2*cos(1/x)))/x怎么做? 求函数极限：lim(x->0) (cos x)^(1/x) lim((cos( √x))^(1/x)) x……0+ lim(x->π)(π-x)cos(1/(x-π)) 二元函数求极限一题!lim ln(x+e^y)/sqrt(x^2 + y^2)(x,y)->(1,0)
