WebIf u=x2+y2 and x=s+3t, y=2s−t, where t does not depend on s, then d2u ds2 is. Q. If u=x2+y2 and x=s+3t, y=2s−t, where s and t are independent of each other, then the value of d2u ds2 is. Q. If u=x2+y2 and x=s+3t, y=2s−t, where s and t are independent of each other, then the value of d2u ds2 is. Q. If u= x−y √x2+y2, then x∂u ∂x+y ... WebAnswer (1 of 5): Let’s t+3t = x → (1) So s+3s = x+2 → (2) Put value of x in equation (2) from equation (1). s+3s = t+3t+2 4s = 4t + 2 4s - 4t = 2 4(s - t) = 2 s - t = 2/4 Therefore, s - t = 1/2

Web(s+ 1)(s+2)(s−3)] = L−1[2 s+1] − L−1[3 s+2]+ L−1[1 s− 3] = 2e−x − 3e−2x +e3x. Example 6.34 (repeated linear factors). Find L−1[s2 + 9s+2 (s−1)2(s+3)]. Solution We write the expression in the form s2 + 9s+2 (s−1)2(s+ 3) = A s−1 + B (s−1)2 + C s+ 3. Solving for the constants yields: A = 2, B = 3, and C = −3. Thus, we ...

Web27 aug. 2024 · A = 3s + 2 s − 2 s = 1 = 3 ⋅ 1 + 2 1 − 2 = − 5. Similarly, we can obtain B by ignoring the factor s − 2 in the denominator of Equation 8.2.2 and setting s = 2 … Web15 mrt. 2024 · Solution: We can define the terms ‘s’ according to relation s i = s i-1 + i. The value of ‘i’ increases by one for each iteration. The value contained in ‘s’ at the i th iteration is the sum of the first ‘i’ positive integers.
