Lim【sin(1/X)*sinX】
lim tan x - sin x / x³ lim eˆ2x - 1 / x
lim(x趋向0)ln(1+sin x)/x^2
lim(x趋向正无穷)[x]*sin(1\x)=?
求极限,lim x趋于0 x * sin 1/x
lim(sin(x^2*cos(1/x)))/x怎么做?
求极限lim(x-->0)x^2 sin(1/x),
求 lim(x→∞)[sin(2/x)+cos(1/x)]^x的极限.
求lim [sin(x^2-1)]/(x-1) x趋向于1的极限.
计算lim x的平方减1分之sin(x-1),x区向1
lim(x——>1)(1-x的平方)/sinπx
lim(1-x^2)/sin兀x 当x趋近于1时的极限
