(x+sin∧2x+tanx)/(sinx+x∧2)在x→0时的极限
(x+sin∧2x+tanx)/(sinx+x∧2)在x→0时的极限
(x+sin∧2x+tanx)/(sinx+x∧2)在x→0时的极限
是0:0型,用洛必达法则求导得:
(1+2sinxcosx+1+sec^2x)/(cosx+2x)
=(1+1+1)/1
=3
∫sin^2x(1+tanx)dx
(tanx-sinx)/x^2sin^2x 极限x--->0
求化简(sinx+tanx)/cos^2x+sin^2x+cosx
f(x)=(1+1/tanx)sin(x)^2化简

提问数学难题求证:sin^2x*tanx+cos^2x/tanx+2sinx*cosx=tanx+1/tanx
若tanx=2,则2sin平方x-3sin(π-x)sin(π/2-x)=
tanx/2=1/2,求sin(x+π/6)
化简(sin2x+2sin^2 x)/1-tanx
(2sin^2X+sin2X)/(1+tanX)怎么化简?
如果tanx=2,那么sin^2(x)+sinx*cosx
tanx/2=1/2求sin(x+π/6)
求极限lim.[( tanx-sinx) /(sin^2 2x)]
已知tanx 2 则sin^2x-sinxcosx
