The term Sn is drived from 'nucleophilic substitution reaction'. 1 means unimolecular, and the rate of the reaction only depend on the concentration of one reactant; 2 means bimolecular, and the rate o...

A curve has parametric equations:

x = 2 + t²                           y = 4t

Find the cartesian equation of this curve.

A cartesian equation of a c...

To start make the equation equal y.
So y = 7x+4
Then rearrange the equation to make x the subject.
Subtract 4 from both sides: y-4 = 7x
Divide by 7: (y-4)/7 = x
Now write it in te...
