Biography:

He was born on September 14 (according to the Julian calendar or 26 according to the Gregorian calendar), 1809. in Ivahniki village of the Lohvytsky district of the Poltava province of the Russian Empire (since 1920, the Yahniki village (Yashnyky village) of the Lohvytsky district of the Poltava region of Ukraine).

Having lost his parents at an early age, he was devoted to his older brother at the Kharkiv Slobid-Ukrainian Gymnasium, which he successfully completed in 1826. In the same year, he entered the physics-mathematics department of the philosophy faculty (according to other data/now the physics -mathematical faculty) of the Imperial Kharkiv University, its physical and mathematical department, graduated from the course in 1829 with a candidate's degree and was left at the university as a tutor in mathematics for students.

Then, in the late 1930s, he worked at the Kharkiv Gymnasium, where he had previously studied, as a teacher of natural sciences and physics, and from 1831 at the Kharkiv Institute of Noble Girls as a physics teacher. In 1832, at the behest of the university council, he began lecturing on optics, then taught the basic principles of mathematics.

In 1835, he defended his dissertation in Kharkiv City: "Considerations about the progress after Euler, made in finding certain integrals, and about their definition", he received a master's degree in pure and applied mathematics and was appointed an adjunct, and six months later he received the position of acting the post of extraordinary professor for teaching applied mathematics until 1839. In 1838, he defended his thesis "On hydraulic wheels" in Kharkiv city for the degree of doctor of pure and applied mathematics.

In April 1839, M. A. Dyachenko was transferred to the St. Volodymyr Imperial Kyiv University, where he continued to serve until his retirement (he served here for over 28 years). In 1840, he was appointed to the rank of full professor. Since 1862 - honored professor of the university.

During 1839-1844, he gave public lectures on practical mechanics in Kharkiv.

He received a number of state awards: in 1845 he was awarded the Order of St. Anna 3rd degree, in 1849 - the Order of St. Anna 2nd degree, in 1857 - the Order of St. Anna 2nd degree with an imperial crown, in 1867 - the Order of St. Vladimir 4 degree, he also received the Award for 25 years of impeccable service, as well as the Bronze medal on the St. Andrew's ribbon in memory of the war of 1853-1856.

At the St. Vladimir Imperial Kyiv University in 1840, taking a chair in which almost all pure and applied mathematics was concentrated, he studied differential and integral calculus and their application to geometry, integration of functions from one variable, using the works of Euler, Lagrange, Cauchy and Leroy , theory of definite integrals, integration of differential equations, algebraic analysis, calculus of variations and , Moignot and Duhamel, as well as according to his own notes. In addition, he taught statics and dynamics, and in the IV course hydrostatics and hydrodynamics, which he taught under the guidance of Poisson, and conducted practical classes on these subjects.

On October 25, 1847, he was elected dean and kept this position until 1855, then he was elected for two more four-year terms, from May 7, 1860 and from November 3, 1862.

In 1863, he received the title of valid state adviser.

He died on April 9 (according to the Julian calendar or 21 according to the Gregorian calendar) on April 1877 in the Kyiv City.

The main works of M. A. Dyachenko belong to the field of mathematical analysis and its application in other sections of mathematics and mechanics. In addition, he fruitfully and actively engaged in astronomy.

For some time he worked together with his younger brother A. A. Dyachenko.
