A differential equation is an equation for a function containing derivatives of that function. For exam-ple, the differential equations for an RLC circuit, a pendulum, and a diffusing dye are given by L d2q dt2 + R dq dt + 1 C q = E 0 coswt, (RLC circuit equation) ml d2q dt2 +cl dq dt

5. Taylor and Laurent series Complex sequences and series An infinite sequence of complex numbers, denoted by {zn}, can be considered as a function defined on a set of positive integers into the unextended complex plane. For example, we take zn= n+ 1 2n so that the complex sequence is {zn} = ˆ1 + i 2, 2 + i 22, 3 + i 23 ...

In MATLAB, single(224) has the same value as single(224 +1). Since single(224 +1) is exactly halfway between the two consecutive machine numbers 224 and 224 +2, MATLAB rounds to the number with a final zero-bit in f, which is 224. 1.10Machine epsilon Machine epsilon (e mach) is the distance between 1 and the next largest number.
