Hace 3 días · The Navier–Stokes equations ( / nævˈjeɪ stoʊks / nav-YAY STOHKS) are partial differential equations which describe the motion of viscous fluid substances. They were named after French engineer and physicist Claude-Louis Navier and the Irish physicist and mathematician George Gabriel Stokes.
Hace 5 días · This standard applies to ethyl, isopropyl, butyl, isobutyl, n-pentyl, isopentyl, and other low-carbon alkyl xanthate sodium or potassium xanthate in determining the amount of xanthate.
Hace 2 días · Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions, [10] and are used to obtain an angle from any of the angle's trigonometric ratios. Inverse trigonometric functions are widely used in engineering, navigation, physics, and geometry .
Hace 1 día · The Schrödinger equation gives the evolution over time of the wave function, the quantum-mechanical characterization of an isolated physical system. The equation was postulated by Schrödinger based on a postulate of Louis de Broglie that all matter has an associated matter wave.
Hace 2 días · It is difficult to separate molybdenite and chalcopyrite by froth flotation due to the good floatability of the two minerals. In this paper, the separation of copper–molybdenum sulfide minerals was realized by using pullulan polysaccharide (PU) as the depressant. The flotation test results showed that the copper concentrate grade increased from 16.24 to 29.86%, and the copper concentrate ...
Hace 3 días · We will learn step-by-step the proof of tangent formula tan (α + β). Prove that tan (α + β) = tanα+tanβ 1−tanαtanβ t a n α + t a n β 1 − t a n α t a n β. Proof: tan (α + β) = sin(α+β) cos(α+β) s i n ( α + β) c o s ( α + β) = sinαcosβ+cosαsinβ cosαcosβ−sinαsinβ s i n α c o s β + c o s α s i n β c o s α c o s β − s i n α s i n β.
Hace 3 días · Formula to Calculate Kurtosis. Despite having a biased estimation if you do not have the full-scale data of a given phenomenon, we will calculate the Kurtosis using the Population Kurtosis Formula in this article. It is denoted mathematically by the following formula: Kurtosis =Fourth Moment value/Square of second Moment value. Where, and, Here,
