求Lim(2sin^nx+3cos^nx)∕(sin^nx+cos^nx),0≤x≤π/2n趋于无穷大求Lim(2sin^nx+3cos^nx)∕(sin^nx+cos^nx),0≤x≤π/2n趋于无

求Lim (2sin^n x+3cos^n x)∕(sin^n x+cos^n x) ,0≤x≤π/2n趋于无穷大
求Lim (2sin^n x+3cos^n x)∕(sin^n x+cos^n x) ,0≤x≤π/2
n趋于无穷大

求Lim (2sin^n x+3cos^n x)∕(sin^n x+cos^n x) ,0≤x≤π/2n趋于无穷大
当π/4

也可以先化简:
Lim (2sin^n x+3cos^n x)∕(sin^n x+cos^n x) =
2 + Lim 1/(sin^n x + cos^n x)
然后分x = 0, π/4 ,π/2; 0
