Indeterminate analysis Math., that branch of analysis which has for its object the solution of indeterminate problems. -- Indeterminate coefficients Math., coefficients arbitrarily assumed for convenience of calculation, or to facilitate some artifice of analysis. Their values are subsequently determined. -- Indeterminate equation Math., an equation in which the unknown quantities admit of an infinite number of values, or sets of values. A group of equations is indeterminate when it contains more unknown quantities than there are equations. -- Indeterminate inflorescence Bot., a mode of inflorescence in which the flowers all arise from axillary buds, the terminal bud going on to grow and sometimes continuing the stem indefinitely; -- called also acropetal, botryose, centripetal, ∧ indefinite inflorescence. Gray. -- Indeterminate problem Math., a problem which admits of an infinite number of solutions, or one in which there are fewer imposed conditions than there are unknown or required results. -- Indeterminate quantity Math., a quantity which has no fixed value, but which may be varied in accordance with any proposed condition. -- Indeterminate series Math., a series whose terms proceed by the powers of an indeterminate quantity, sometimes also with indeterminate exponents, or indeterminate coefficients.
