72 Partial Derivatives: Problem 16 Next Previous Problem List (1 point) Suppose the f(x, y) is a smooth function and that its partial derivatives have the values, f(0,-4) 5 and f,(0, -4) =-1. Given that f(0,-4) = 0, use this information to estimate the value of f(1,-3) Note this is analogous to finding the tangent line approximation to a function of one variable. In fancy terms, it is the first Taylor approximation. Estimate of (integer value) f(1,-3)

2. Inorder for your phone to calibrate, it's important to have a good idea of how different T and T really are but also to be able to do that on the fly, without too much computation TO do this, we'll use linear approx inution. Specifically, we'll letェ= u2/02, so that and then approximate the function 1/V1-2. (a) Calculate the equation of the tangent line to the function f(z) = atェ= 0. (b) Use the tangent line to approximate the...

Enzyme Activity (ml) Effect of pH on (amylase) enzyme activity. For determination of optimum assay pH of the enzyme reaction, 0.05 M Na2HPO4-NaH2PO4 buffer was used. The reaction was carried out for 10 min at 50°C in a shaking water. The enzyme activity was measured and the results are presented on graph, Bars represent means standard deviations for three replicates. 1. What do the error bars in this graph represent?...
