The Picomath suite of programs will perform a wide range of algebraic manipulations, and expressions can be symbolically differentiated or integrated.

POLYNOM can expand and simplify, differentiate, or integrate, a polynomial expression such as:

(2x - y). (x + y)^{2} - (28z - 1)^{2}

into the equivalent polynomial:

2x^{3} + 3x^{2}y - y^{3} - 784.z^{2} + 56.z - 1

RATIONAL can expand and simplify an expression such as:

1 +1-1+2xx-1 x-1 x^{2}-1

into the equivalent ratio of two polynomials, reduced to lowest terms:

x+1x-1

TRIGONOM can expand and simplify,differentiate, or integrate, a trigonometric expression such as:

1 + tan1 + cot^{2}x^{2}x

into the equivalent standard form:

sec^{2}x - 1

FOURIER can perform trigonometric transformations into a linear combination of sines and cosines of integer multiples of x. For example:

64 sin^{4}x cos^{3}x

will be transformed into:

3 cos x - 3 cos (3x) - cos (5x) + cos (7x)

Memory requirements: Programs 5K, graphics ½K, need floating-point.
