Can you identify the equation of this line? [br][br]Click the checkbox to see if you are right.[br][br]You can also show the circle and radius that help you to determine the equation.[br][br][b]The Equation of a Line Not Through the Pole is:[/b][br][math]r\cos\left(\theta-\alpha\right)=d[/math][br][br]Where the line is tangent to a circle of radius [math]d[/math] at the point [math]\left(d,\alpha\right)[/math].[br][br]If you can identify the point of tangency, you can find the equation.
