WebMay 29, 2024 · The cosecant ( ), secant ( ) and cotangent ( ) functions are 'convenience' functions, just the reciprocals of (that is 1 divided by) the sine, cosine and tangent. So. Notice that cosecant is the reciprocal of sine, while from the name you might expect it to be the reciprocal of cosine! Everything that can be done with these convenience ...

WebSep 7, 2024 · Find the equation of a line tangent to the graph of \(f(x)=\cot x \) at \(x=\frac{π}{4}\). Solution. To find the equation of the tangent line, we need a point and a slope at that point. To find the point, compute \(f\left(\frac{π}{4}\right)=\cot\frac{π}{4}=1\). Thus the tangent line passes through the point \(\left(\frac{π}{4},1\right)\). WebI know that by the residue theorem: Res ( cos π z, n) = lim z → n ( z − n) f ( z) And i know (well i think) that the answer is: Res ( cos π z, n) = cos π n π cos π n. However i'm completely stuck with how to use the simple pole residue theorem, and how to sub in, or what i do with the theorem to show that this is the answer. formation compressive strength
