Correct 3D data triangulation is a non-trivial task due to potential scan shadows, vegetation, sharp topography changes and random errors.

Although cut detection appears to be a simple task for a human being, it is a non-trivial task for computers.

This makes alignment a non-trivial task.

One could further say that expertise is the quality exhibited by people whom we believe demonstrate an above-average ability to perform a non-trivial task (see Expert for tongue-in-cheek examples).

This can be a non-trivial task, for example as with parallel processes or some unusual software bugs.

Since Graham experiments, it is well known that avoiding of convection is necessary and this may be a non-trivial task.

This is a non-trivial task.

Accurate and quantitative measurement of these parameters from the SSM/I TBs is, however, a non-trivial task.

The non-trivial task of constructing a spin foam model is then reduced to the question of how this simplicity constraint should be imposed in the quantum theory.

Programming robots is a non-trivial task.
