A conditional equation (usually referred to simply as an equation) is a literal equation that is not true for all values of the variable, e.g., only the value 2 for x makes true the equation x+3=5. To solve an equation is to find the value or values of the variable that satisfy ...
The general mathematical formulation of the laws of conservation of mass and energy and the equation of motion are derived for a moving thread. Within the thread only forces in tangential direction are considered: internal stresses perpendicular to the tangential direction are left out of consideration...
Morons from Outer Space (1985) IMDB ** A mathematician writes an incomplete equation to test one of the moron's mathematical abilities. "Now, Can you complete that?" " ... Can you?" "Of course." "Then what are you asking me for?" ...
The motion of a basketball as it leaves a player's hand and passes through the net can be modelled using the equation h=2+1.1x−0.1x2 , where h m is the height of the basketball above the groupd and x m is the horizontal distance travelled. " 根据图可以知道在y轴上的y=2的地方...
By normalisation, \(X_i(\rho ) = 0\) for \(i\in [p+1,q]\) which can also be seen from Eq. (75) by applying a similar argument as for \(b_i=0\). Equation (82) combined with Eq. (70) gives the quoted form of the map. \(\square \)3 Equivalent Definitions of Duality...

Their paper reflected an attempt to formulate a correlation equation for the prediction of compaction characteristics such as the maximum dry density and the optimum moisture content. Gurtug and Sridharan (2004) suggested a correlation for clayey soils; the maximum dry density was 0.98 times the ...
[18,43]. As an initial step in our research, we make an integrability analysis of system (1) by using Darboux theory of integrability [9]. We show that system (1) does not have any polynomial, rational or Darboux first integrals, which means any search for a closed-form, analytical ...
