texpand

Expands a transcendental expression.

 

texpand(Expr)

 

Example:

 

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

 

2*cos(x)*sin(x))

Exp & Ln

 

ey*lnx xy

Returns an expression of the form en*ln(x) rewritten as a power

 

of x. Applies en*ln(x)=xn.

 

exp2pow(Expr)

 

Example:

 

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

xy ey*lnx

Returns an expression with powers rewritten as an

 

exponential. Essentially the inverse of exp2pow.

 

pow2exp(Expr)

 

Example:

 

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

exp2trig

Returns an expression with complex exponentials rewritten in

 

terms of sine and cosine.

 

exp2trig(Expr)

 

Example:

 

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

expexpand

Returns an expression with exponentials in expanded form.

 

expexpand(Expr)

 

Example:

 

expexpand(exp(3*x)) gives exp(x)^3

Sine

 

asinx acosx

Returns an expression with asin(x) rewritten as π/2– acos(x).

 

asin2acos(Expr)

 

Example:

 

asin2acos(acos(x)+asin(x)) returns π/2
