Determining the grazing angle with respect to a planar surface is trivial, but the computation for almost any other surface is significantly more difficult.

The color, consistency, acidity, and other characteristics of the discharge may be predictive of the causative agent. Determining the agent is especially important because women may have more than one infection, or have symptoms that overlap those of another infection, which dictates different treatment processes to cure the infection.

Determining a suitable classifier for a given problem is however still more an art than a science.

Determining whether socioeconomic or political factors are more important in explaining government action is a familiar theme.

Determining the appropriate treatment for noncyclical breast pain is more difficult, not only because it is hard to pinpoint where the pain is coming from, but also because the pain may not have hormonal causes and very often does not respond to hormonal treatment.

Determining what average input means is difficult, and often that average input has properties which make it difficult to characterise mathematically ( consider, for instance, algorithms that are designed to operate on strings of text ).

Determining whether a given food should be classified as bread, cake, or pastry can be difficult.

Determining the number of films he made during the early part of his career is difficult because the ad copy rarely named him.

" Although a Human Effects Advisory Panel was established in 1998 to provide independent assessment on human effects, data, and models for the use of ' non-lethal weapons ' on the general population, the TECOM Technology Symposium in 1997 concluded on non-lethal weapons: " Determining the target effects on personnel is the greatest challenge to the testing community ," primarily because " the potential of injury and death severely limits human tests.

" Determining the link between data breaches and identity theft is challenging, primarily because identity theft victims often do not know how their personal information was obtained ," and identity theft is not always detectable by the individual victims, according to a report done for the FTC.

Determining a property or site location based upon Magnetic North will result in inaccuracies because true magnetic north fluctuates.

Determining whether news is " good " or " bad " must be determined by the price action of the stock, because the market reaction may not match the tone of the news itself.

Determining which amino acid forms the N-terminus of a peptide chain is useful for two reasons: to aid the ordering of individual peptide fragments ' sequences into a whole chain, and because the first round of Edman degradation is often contaminated by impurities and therefore does not give an accurate determination of the N-terminal amino acid.

Determining the optimal parameters in a model of this type is not trivial, and local numerical optimization methods such as gradient descent can be sensitive to initialization because of the presence of local minima of the training criterion.
