Find Root
Function root-nder (like the Solve app). Finds the value for the given variable at which expression most
nearly evaluates to zero. Uses guess as initial estimate.
FNROOT(expression,variable,guess)
Example:
FNROOT((A*9.8/600)-1,A,1) returns 61.2244897959.
Percentage
x percent of y; that is, x/100*y.
%(x,y)
Example:
%(20,50) returns 10

in Home modes.
ARG(x+y*i)
Example:
ARG(3+3*i) returns 45 (degrees mode)
Conjugate
Complex conjugate. Conjugation is the negation (sign reversal) of the imaginary part of a complex number.
CONJ(x+y*i)
Example:
CONJ(3+4*i) returns (3-4*i)
