Asymptotic expansion and bounds for complete elliptic integrals
In the article, we present several new bounds for the the complete elliptic integrals K (r)= ∫ π/2 0 (1−r2 sin2 θ )−1/2dθ and E (r)= ∫ π/2 0 (1−r2 sin2 θ )1/2dθ , and find an asymptotic expansion for K (r) as r → 1 , which are the refinements and improvements of the previously well-known results.

期刊介绍:
''Mathematical Inequalities & Applications'' (''MIA'') brings together original research papers in all areas of mathematics, provided they are concerned with inequalities or their role. From time to time ''MIA'' will publish invited survey articles. Short notes with interesting results or open problems will also be accepted. ''MIA'' is published quarterly, in January, April, July, and October.
