10.3.2  Expanding exponentials

The exponential function applied to a sum can be converted into a product of exponentials; namely,

The expexpand command does this conversion. For expansions in other bases, see Section 10.3.6.

• expexpand takes expr, an expression.
• expexpand(expr) returns the expression expr with exponentials (base e) of sums rewritten as products of exponentials.
