lncollect(ln(x)+2*ln(y)) returns ln(x*y^2)

Rewrites an expression containing a power that is a sum or product as a product of powers. Applies a^(b

+c)=(a^b)*(a^c).

powexpand(Expr)

powexpand(2^(x+y)) yields (2^x)*(2^y)

Expands a transcendental expression.

texpand(Expr)

texpand(sin(2*x)+exp(x+y)) returns exp(x)*exp(y)+ 2*cos(x)*sin(x))

Rewrite – Exp & Ln

Returns an expression of the form e

rewritten as a power of x. Applies e

exp2pow(Expr)

exp2pow(exp(3*ln(x))) gives x^3

Returns an expression with powers rewritten as an exponential. Essentially the inverse of exp2pow.

pow2exp(Expr)

pow2exp(a^b) gives exp(b*ln(a))

Returns an expression with complex exponentials rewritten in terms of sine and cosine.

exp2trig(Expr)

exp2trig(exp(i*x)) gives cos(x)+(i)*sin(x)
