Study Notes
Linear Asymptotes
- An asymptote is represented by the equation ( y = mx + c ) if certain conditions are met.
- Condition (i): ( \phi_{n}(m) = 0 ) indicates that one root is infinite.
- Condition (ii): ( c\phi_{n}'(m) + \phi_{n-1}(m) = 0 ) provides the corresponding value of ( c ) for the given ( m ).
- An ( n )-th degree polynomial ( \phi_{n}(m) ) will yield ( n ) values for the slope ( m ), denoted as ( m_{1}, m_{2}, \ldots, m_{n} ).
- The corresponding intercepts ( c ) can be calculated using:
- ( c_{1} = \frac{\phi_{n-1}(m_{1})}{\phi_{n}'(m_{1})} )
- ( c_{2} = \frac{\phi_{n-1}(m_{2})}{\phi_{n}'(m_{2})} )
- Continue this for all ( m ) values.
- Thus, the asymptotes of the curve are:
- ( y = m_{1}x + c_{1} )
- ( y = m_{2}x + c_{2} )
- And so on for all ( n ) asymptotes.
Rules and Corollaries
- To identify the slopes, substitute ( x = 1 ) and ( y = m ) into the highest degree terms to find ( \phi_{n}(m) = 0 ).
- For ( \phi_{n-1}(m) ), repeat the process using terms of degree ( n-1 ) and differentiate ( \phi_{n}(m) ) for slope values.
- Corollary 1: Given ( \phi_{n}(m) = 0 ) is an ( n )-th degree equation, there are exactly ( n ) values of ( m ), leading to ( n ) asymptotes that may be real or imaginary.
- Corollary 2: For curves defined by odd-degree equations, there is at least one real root, as imaginary roots occur in pairs. Thus, curves of odd degree cannot be closed and will always have an odd number of real asymptotes.
