Web2} and so there are two solutions y 1= em1xand y 2= em2x. Then the general solution is given by y = Aem1x+Bem2x, with A,B constants. (6) 2.1.3 Examples (i) d2y dx2 − 4y = 0. Look for solutions of the form y(x) = emxand so m2− 4 = 0. Thus m = ±2 and the general solution is y(x) = Ae2x+Be−2x. (ii) d2y dx2 + y = 0. WebIf d 2 y/dx 2 = 0, you must test the values of dy/dx either side of the stationary point, as before in the stationary points section. Example Find the stationary points on the curve y = x 3 - 27x and determine the nature of the points: At stationary points, dy/dx = 0 dy/dx = 3x 2 - 27 If this is equal to zero, 3x 2 - 27 = 0
WebAssuming that, d x d t = 2 t and d y d t = 2 t + 3 t 2. So that d y d x = 2 t + 3 t 2 2 t = 1 + ( 3 / 2) t. To find the second derivative, do exactly the same thing again, differentiating the first derivative with respect to x. Let Y ′ = 1 + ( 3 / 2) t, d 2 y d x 2 = d Y ′ d x = d Y ′ d t d x d t. WebQuestion: Nondimensionalize this equation: 0 = k*d2T/dy2 + G2y2/u0 (eB(T/T0 - 1)). Choosing Y = y/(h/2) and phi(Y) = B(T/T0 -1) You should find 0 = d2phi/dY2 + LY2ephi. What is L? What boundary conditions apply to this ODE. Nondimensionalize this equation: 0 = k*d 2 T/dy 2 + G 2 y 2 /u 0 (e B(T/T 0 - 1)).
WebExplanation: Q1 = k1 A1 d t1/δ1 and Q2 = k2A2 d t2/δ 2 Now, δ1 = δ2 and A1 = A2 and d t1 = d t2 So, Q1/Q2 = ½. 4 - Question The interior of an oven is maintained at a temperature of 850 degree Celsius by means of a suitable control apparatus.
