You want to fly your small plane due north, but there is a 75-kilometer wind blowing from west to east. a. Find the direction angle for where you should head the plane if your speed relative to the ground is 310 kilometers per hour. b. If you increase your airspeed, should the direction angle in part (a) increase or decrease? Explain your answer.
Use a graphing utility to graph the polar equation. $$r=2+2 \sin \theta$$
In calculus, it can be shown that $$e^{i \theta}=\cos \theta+i \sin \theta$$ In Exercises \(87-90,\) use this result to plot each complex number. $$ e^{\frac{\pi i}{4}} $$
Test for symmetry and then graph each polar equation. $$r=2-4 \cos 2 \theta$$
