The key to this problem is to apply sec to both sides, and then differentiate implicitly: sec(y)=x; dsec(y)/dx = 1; tan(y)sec(y)dy/dx = 1; dy/dx = 1/(tan(y)sec(y)). Then using the fact that sec(y)=x and t...

There are three types of isomerism:1) Structural isomerism - Occurs when compounds which have the same molecular formula (eg. C4H9Br1) but have different atomic arrangements. Eg. CH2Br-CH2-CH2-CH3CH3-CHBr...
