Trigonometric functions are simplified in several ways. Hyperbolic functions of their inverses and of negative-looking arguments are also handled, as are exponentials of inverse hyperbolic functions. No simplifications for inverse trigonometric and hyperbolic functions are known, except for negative arguments of arcsin , arctan , arcsinh , and arctanh . The error functions erf and erfc are simplified when their arguments are negative-looking or are calls to the conj function. Equations and inequalities are simplified by cancelling factors of products, quotients, or sums on both sides.
Inequalities change sign if a negative multiplicative factor is cancelled.
Factors are cancelled from inequalities only if they are nonzero and their sign is known. Go to the first , previous , next , last section, table of contents .
