Improper (difficult) integrals at SwissMicros Calculator Forum

[peacecalc]

Hello Irdheat,

thank you for clarification. The arc-length of the function handled in this thread is about 4E19 for x in [-1; 1] and the main part comes from [0,95 ; 1] the number of oszillations is in the same magnitude (3E18). If one has a look to the derivative, it is seen, that the magnitude of the arclength of the function is not only oszillating with the sin, it is superimposed by a cos, too.

Every physicist or engineer could be glad that his problem needn't such an integral for solution.
