tExpand Returns a transcendental expression in expanded form.
tExpand(Expr)
Example:
tExpand(sin(2*x)+exp(x+y))
gives
2*cos(x)*sin(x)+exp(x)*exp(y)
Exp & Ln
e y*lnx → x y Returns an expression of the form exp(n*ln(x)) rewritten as a
power of x.
exp2pow(Expr)
Example:
exp2pow(exp(3*ln(x)))
gives
x^3
x y → e y*lnx Returns an expression with powers rewritten as an
exponential.
pow2exp(Expr)
Example:
pow2exp(a^b)
gives
exp(b*ln(a))
exp2trig Returns an expression with complex exponentials rewritten in
terms of sin and cos.
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 arcsin(x) rewritten as pi/2-
arccos(x).
asin2acos(Expr)
Example:
asin2acos(acos(x)+asin(x))
gives
-
