Magazine Problem 91
Use the result of Exercise 90 to find the angle \(\psi\) between the radial and tangent lines to the graph for the indicated value of \(\theta\). Use a graphing utility to graph the polar equation, the radial line, and the tangent line for the indicated value of \(\theta .\) Identify the angle \(\psi\). $$ r=2(1-\cos \theta), \theta=\pi $$
Problem 92
Use the result of Exercise 90 to find the angle \(\psi\) between the radial and tangent lines to the graph for the indicated value of \(\theta\). Use a graphing utility to graph the polar equation, the radial line, and the tangent line for the indicated value of \(\theta .\) Identify the angle \(\psi\). $$ r=4 \sin 2 \theta, \theta=\pi / 6 $$
Problem 93
Use the result of Exercise 90 to find the angle \(\psi\) between the radial and tangent lines to the graph for the indicated value of \(\theta\). Use a graphing utility to graph the polar equation, the radial line, and the tangent line for the indicated value of \(\theta .\) Identify the angle \(\psi\). $$ r=\frac{6}{1-\cos \theta}, \theta=2 \pi / 3 $$
Problem 94
Use the result of Exercise 90 to find the angle \(\psi\) between the radial and tangent lines to the graph for the indicated value of \(\theta\). Use a graphing utility to graph the polar equation, the radial line, and the tangent line for the indicated value of \(\theta .\) Identify the angle \(\psi\). $$ r=5, \theta=\pi / 6 $$
Problem 96
Determine whether the statement is true or false. If it is false, explain why or give an example that shows it is false. If \(\left(r, \theta_{1}\right)\) and \(\left(r, \theta_{2}\right)\) represent the same point on the polar coordinate system, then \(\theta_{1}=\theta_{2}+2 \pi n\) for some integer \(n\).
