Fundamental substitution for trigonometric integration

Nature laughs at the difficulties of integration	Beer is better for you than milk	Derivation is a science, integration is an art	impossible integral
elliptic integral standard forms	The Absolute Differential Calculus	The Difficulty lies in Integration	Perhaps God is our future, not our past
Mind and Truth	You know you want me, baby!	indefinite integral	confluent hypergeometric function
Integration	partial fraction	burqa	error function
integrating sin(ln(x))	integration by parts	riverrun	retina
trigonometry	fundamental	Calculus
