: Let Z X2 2y2 Supposer And Y Are Both Functions Of Time T With Y 2e5t At The Instant When X 1 And Y 2 The Rat 1 (20.3 KiB) Viewed 24 times

Let z = x2 + 2y2. Supposer and y are both functions of time t, with y=2e5t. At the instant when x = 1 and y = 2, the rate of change of r with dz respect to t is 5. Use the appropriate version of the chain rule to find at dt that instant. (The answer is a number.)
