WebTo derive the differential equation describing the relationship between stress and strain for the Maxwell model, we need to differentiate the stress-strain relationship with respect to time: The first term on the right-hand side represents the stress due to the elastic deformation, which is proportional to the rate of change of strain. WebPoiseuille’s law derivation begins from the Navier-Stokes equations. Note that we cannot start from the Euler equations, as we must consider the viscosity. According to the Euler equations, the flow rate would be infinite due to zero viscosity, something which cannot be observed in reality. Therefore, we must keep the viscous forces in the ...

WebThe investment function is expressed as: I = I̅ – cr, C<0, where r is the rate of interest and c measures the interest response of investment, I̅ denotes autonomous investment, that is, investment spending which is independent of both income and the rate of interest. WebThere is a direct relation between the three parameters, , τ, and λ which is follows: = = where ln (2) happens to be the natural logarithm of 2 (approximately 0.693). Half Life Formula Derivation First of all, we start from the exponential decay law which is as follows: N (t) = N0 Furthermore, one must set t = and N () = ½ N0.

WebMay 1, 2024 · Here we use quotient rule as described below. Quotient rule states if f (x) = g(x) h(x) then df dx = dg dx × h(x) − dh dx ×g(x) (h(x))2 Here g(x) = 3 −2x − x2 and hence dg dx = −2 −2x and as h(x) = x2 −1, we have dh dx = 2x and hence df dx = ( −2 −2x) × (x2 − 1) − 2x × (3 − 2x −x2) (x2 − 1)2 = −2x3 − 2x2 + 2x + 2 − 6x +4x2 + 2x3 (x2 − 1)2 WebDeriving Equations Calculus Absolute Maxima and Minima Absolute and Conditional Convergence Accumulation Function Accumulation Problems Algebraic Functions … WebSep 10, 2024 · Subscribe 14K views 5 years ago MATHS In this video we look at how to derive equations and expressions from sentences.
