Linearizing exponentials

10.3.4 Linearizing exponentials

The lin command will linearize expressions involving exponentials; namely, it will replace products of exponentials by exponentials of sums. It will first replace any hyperbolic functions by exponentials.

lin takes expr, an expression.
lin(expr) returns the linearized version of expr.

Examples

lin(sinh(x)^2)

e^2 x

−

e^−2 x

lin((exp(x)+1)^3)

e^3 x+3 e^2 x+3 e^x+1
