The phrase "a sum of terms" is correct and usable in written English.
It can be used in mathematical contexts to refer to the total obtained by adding together individual terms.
Example: "In algebra, the expression can be simplified to a sum of terms that are easier to work with."
Alternatives: "total of components" or "aggregate of elements".
And what we can consider doing is expanding that out in a partial fraction expansion, namely as a sum of terms.
Sometimes it is convenient to represent the internal energy as a sum of terms that can be interpreted as kinetic energy, potential energy, and chemical energy.
The cost function is a sum of terms quadratic in the differences between the data and their model counterparts and terms quadratic in the temperature and salinity time rate of change as evaluated using the model equations.
The response is given by a sum of terms involving the interaction of a pair of global modes, the contribution of each pair depending on the appropriate elements of the distribution matrices.
First, the part of the multiple scales method used to reduce the problem to a set of differential equations is used to express the solution as a sum of terms of various harmonics with unknown, time dependent coefficients.
If this is the case, not only is our six-digit palindrome divisible by 11, but every even digit palindrome is, since we will be able to convert, as above, all even digit palindromes into a sum of terms, such that each term is a multiple of a number of the form 100…001, with even number of zeros.
The expansion coefficients are given as a sum of three terms; each of the terms obeys a simple three-term recurrence relation.
Equation (9) has two terms, a sum of squares term and a quadratic term in b.
That is to say, the output of the gate will be represented by a quantum state that is a sum of two terms, where the first term represents the output of the control and target for the first qubit, and the second term represents the output of the control and target for the second orthogonal qubit.
Goldscore (another Gold scoring function) [3, 32] is a sum of empirical terms and force field-like terms for van der Waals and Coulombic energies.
Algebraically, then, what that corresponds to is representing the sequence as a sum of individual terms as I've indicated here or in terms of a general sum, the sum of x[k] delta[n-k].
