The phrase "by mathematical calculation" is correct and commonly used in written English.
It means using mathematical methods or techniques to solve a problem or find an answer. You can use it when discussing a solution to a problem or explaining how a result was obtained. Example: The researcher was able to determine the correct angle for the experiment by mathematical calculation, leading to consistent and accurate results.
The formula involves the adding up of the long sentences, prepositional phrases and hard words in a given passage & then determining the readability by mathematical calculation.
The engineer, inspired by the law of economy and led by mathematical calculation, puts us in accord with the laws of the universe.
It was doubtless the difference in educational methods that prompted Le Corbusier to state: The engineer, inspired by the law of economy and led by mathematical calculation, puts us in accord with the laws of the universe.
Since designs can be established by mathematical calculations and methods, it is generally assumed that engineering failures cannot occur.
Based on mathematical calculations, the compressed side can be accurately defined; however, the uncompressed side cannot be easily defined by mathematical calculations and can lead to errors in the design.
Supported by mathematical calculations, we designed a high-density mutagenesis procedure for the generation of a mutant library of which a limited number of random clones would suffice to exactly localize amino acid residues essential for a particular protein-protein interaction.
By mathematical calculations we obtain that (5.1) is equivalent to the model min F x), (5.2) where (F x)=frac{|h(x)|^{2}}{2}), and (|cdot |) is the Euclidean norm.
NORC, the world's fastest calculating machine, was said yesterday to be capable of predicting weather for an entire hemisphere for thirty to sixty days by a mathematical calculation taking about one day to complete.
The simulation required the development by Wang of some new computational tools - "tricks," she modestly calls them, to resolve unsteady flows and forces, which are governed by a mathematical calculation called the Navier-Stokes Equation - and hundreds of hours of number-crunching by a supercomputer.
The binding data were analyzed by a mathematical calculation based on the 1∶1 (Langmuir) binding model (Table 1).
To maintain surprise, no registration rounds were fired, the guns being laid solely by means of mathematical calculation and weather reports.
