WebIn L (x) = f (a) + f' (a) (x - a), the point is (a, f (a)) instead of (x1, y1). As you already know, f' (a) represents the slope (m) of the equation at the point where x = a. Therefore: y - y1 = m (x - x1) is the same as f (x) - f (a) = f' (a) (x - a) Add f (a) to both sides: f (x) = f (a) + f' (a) (x - a) WebApr 25, 2024 · Linearizing a Power Function Write down the power function.

The power law is usually used to model shear thinning by making 0 < n < 1, though it can also be used for modelling shear-thickening by making n > 1. A smaller value of n represents a higher shear thinning of the fluids. When n = 1, the fluids become Newtonian fluids. highest rated bike cycle computerWebThe standard trick is to linearize the model by taking logs: ln (y) = ln (a) + b t.
