化简sin^x*tanx+cos^x*1/tanx+2sinx*cosx化简sin^x*tanx+cos^x*1/tanx+2sinx*cosx化简sin^x*tanx+cos^x*1/tanx+2s

化简sin^x*tanx+cos^x*1/tanx+2sinx*cosx
化简sin^x*tanx+cos^x*1/tanx+2sinx*cosx

化简sin^x*tanx+cos^x*1/tanx+2sinx*cosx
sin^x*tanx+cos^x*1/tanx+2sinx*cosx
=(sin^x*tan^x +cos^x)/tanx +2sinxcosx
=[(sinx)^4+(cosx)^4]/[(cos^x*tanx] + 2sinxcosx
=[(sin^x+cos^x)^2-2sin^x*cos^x]/(sinxcosx) +2sinxcosx
=[1/(sinxcosx)]-2sinxcosx + 2sinxcosx
=1/(sinxcosx)
=2/sin2x
