Using a trig identity, write {eq}x(t)=-2\cos(8t)+3\sin(8t) {/eq} using only one cosine function. Abusing the angle-sum formula We can simplify {eq}a\cos\theta+b\sin\theta {/eq} into either {eq}k\cos(\theta+x) {/eq} or {eq}k\sin(\theta+x...
In DECLARE EXTERNAL FUNCTION <name>, any <name> can be given for use by the SQL statements that are going to call it. However, as with any UDF, the name in the array (in this case, byte_len) must be referenced in the function declaration by the ENTRY_POINT attribute of the DECLARE...
