Chapter 1: Q2RP (page 1)

In problems 1-6, identify the independent variable, dependent variable, and determine whether the equation is linear or nonlinear.

3r-cos胃drd胃=sin胃

Short Answer

Expert verified

猞� The Independent variable is 胃.

猞� The dependent variable is r.

猞� The equation is linear.

Step by step solution

01

Identifying the dependent and independent variables.

Clearly, the independent variable is 胃 while the dependent variable is r.

02

Determining whether the equation is linear or nonlinear

Since the dependent variable r and its derivatives appear in additive combinations of their first powers, the equation is linear.

Hence, the Independent variable is 胃.The dependent variable is r. And the equation is linear.
