Phew! Working with trig functions isn’t always easy, but at least it’s manageable. 3. It’s computationally efficient. If you’re doing a computer graphics, and frequently calculating sine/cosine (for dot products let’s say), trig identities are useful shortcuts. In the past, these ide...

Depending on the problem, polar or rectangular coordinates are more useful. Euler's formula lets us convert between the two to use the best tool for the job. Also, becauseeixcan be converted to sine and cosine, we can rewrite formulas in trig as variations on e, which comes in very hand...

A method due to McNamee is used to derive a generalization of a formula of Davis for the error in approximating an integral of a periodic analytic function over a complete period by the generalized trapezoidal rule. A feature of this gen... J Mcnamee - 《Mathematics of Computation》 被引量...
If you use calculations for a period of time that continually changes — such as determining sales for the month — use the OFFSET function in Excel to set up a dynamic range that changes as each day's sales figures are added. By itself, theSUM functioncan usually accommodate the insertion...
FFA Cytotoxic Mechanism Lipase-digested formula cytotoxicity was prevented only if a lipase inhibitor, orlistat, was added at the beginning of the diges- tion period rather than at the end of digestion, confirming that lipase activity during digestion is the key requirement for cell death to occur...
