Objectives:
=> To understand algebraically and graphically exponential and logarithms.
=> To understand and use linear (Cartesian) and semilog graph paper for the representation of data.
=> To review differential and integral calculus
=> To understand and use spreadsheets
=> To understand the theory, instrumentation and application of spectrophotometric methods of analysis
Defn: N = bx or N = b^x
Figure II1
Note use of ^
N is the number, b is the base, often 10 but also e ( = 2.7183), and x is the exponent
With common base, exponents can be added or subtracted
e.g. a^{x} * a^{y} = a^{(x+y)} to perform multiplication or division.
