Reading questions
Reading question 11.1 The reading refers to a function like \(f()\):
\[f(t) \equiv74\ e^{-0.0173\,t} + 25 \] There are three parameters in the function. Which one (if any) is a nonlinear parameter.
74 -0.0173 25 None of them.
Reading question 11.2 In the functions \(A e^{kt} + B\) or \(A \sin(\frac{2\pi}{P} t) + B\) a name is used for the parameter in the role of \(B\). What is it?
“lift” “shift” “baseline” “ground”
question id: B-param
Reading question 11.3 The reading refers to cells in the eye’s retina that mediate the perception of color. What is the name of these cells?
cones rods t-cells ganglions filters
question id: eye-cells
Reading question 11.4 Newton’s Law of Cooling, introduced in the Reading, describes the change in temperature of a hot object put in a cool environment. It can be expressed by a function:
\[\text{change\_in\_temp}(T) \equiv - a\, T\]
- The formula in the definition of change_in_temp() is a version of a function encountered in earlier chapters. What is the name used for that function in the earlier chapters?
straight-line identity proportional linear
question id: newton-cooling-a
- There is a minus sign in the function formula for change_in_temp(). Explain
question id: newton-cooling-b
