Polyesters are a class of polymers that have an organic molecule dubbed a practical cluster in their main chain, which renders them perishable. The Wallace Carothers team created poly(caprolactone) (PCL), one of the first polymers, in the 1930s. PCL, like new tissue scaffold host systems, ...
Now, the second derivative of $\arctan $ can be directly calculated by the Quotient Rule formula. The formula of the Quotient Rule is give as, $f'\left( x \right)=\dfrac{g'\left( x \right)h\left( x \right)-h'\left( x \right)g\left( x \right)}{{{\left| h\left( x...

Polyphenols are a structural class of mainly natural organic chemicals, whose structure comprises multiple phenolic units. Each particular polyphenol has a unique number and structure of phenolic rings, which imparts its physical, chemical and biological properties. Polyphenol antioxidants are very diverse...
Despite the potential limitations of the classification of aminopyridines, given the unique characteristics of their structure, we have opted to categorize them within a distinct class. Notably, the structure of these compounds shares notable resemblance with that of Formula A (Fig. 6A). By s...
Faà di Bruno's formula gives an explicit formula for the th derivative of the composition . The June 2, 1996 comic strip FoxTrot by Bill Amend (Amend 1998, p. 19; Mitchell 2006/2007) featured the following derivative as a "hard" exam problem intended for a remedial math class but acc...
