There are many built-in mathematical functions for real and complex numbers, e.g.,
Type SetImaginaryNumber( i ) to define i as sqrt(-1).
Type Help MathFunctions for a list of mathematical functions.
someComplexNumber = sin(pi/4) + exp(3) + cosh(2) + abs(-3) + sqrt( ImaginaryNumber() )
Use the Expand command to eliminate parentheses, e.g.,
p = Expand( (1+t)*(2+t^2)*(3+t^3) )The response to this input is equal to
p = 6 + 6*t + 3*t^2 + 5*t^3 + 2*t^4 + t^5 + t^6To evaluate p for t = 2.3, issue the command
p23 = Evaluate( p, t = 2.3 )To find the ordinary time-derivative of p, enter
derivative = Dt( p )The 5 roots of the 5th-order polynomial in DpDt for t are calculated with
roots = GetPolynomialRoots( DpDt, t, 5 )
