project using uA741

hey i v just startd learnin abt various circuits(basic ones like wave form generators,filters,rectifiers) usin uA741...we hav been askd 2 do a project based on ths knowledges...on a pcb...splder the cpmponents and submit...i would like to have some suggestions for it...

go to this page:

Scrol the left hand side menu, about the middile for OP-AMP(pdf), download, read and don miss pages 72, 73 and 74. It shows an animated OP-AMP with varying voltage on the inputs and the voltage on the output.

is it possible to use the same circuits and components(their values) for uA741???can you explain me the working of double integrator
