To determine Find the slope of the curve at the given polar points and sketch the curve along with its tangent lines at the points. Explanation Given data: The given polar points are written as follows: ( r , θ ) = ( cos 2 θ , 0 ) ( r , θ ) = ( cos 2 θ , ± π 2 ) ( r , θ ) = ( cos 2 θ , π ) Formula used: Write the expression for slope of the curve as follows: d y d x | ( r , θ ) = r ′ sin θ + r cos θ r ′ cos θ − r sin θ (1) Calculation: Rewrite the given polar points as follows: ( r , θ ) = ( cos 2 θ , 0 ) , ( cos 2 θ , π 2 ) , ( cos 2 θ , − π 2 ) , ( cos 2 θ , π ) = ( cos 2 ( 0 ) , 0 ) , ( cos 2 ( π 2 ) , π 2 ) , ( cos 2 ( − π 2 ) , − π 2 ) , ( cos 2 ( π ) , π ) = ( 1 , 0 ) , ( − 1 , π 2 ) , ( − 1 , − π 2 ) , ( 1 , π ) Therefore, the given polar points are ( 1 , 0 ) , ( − 1 , π 2 ) , ( − 1 , − π 2 ) , and ( 1 , π ) . From the give polar points, r is given as follows: r = cos 2 θ Differentiate on both sides of the expression as follows: d r d θ = d d θ ( cos 2 θ ) r ′ = − 2 sin 2 θ Substitute cos 2 θ for r and − 2 sin 2 θ for r ′ in Equation (1) to obtain the slope of the curve. d y d x | ( r , θ ) = ( − 2 sin 2 θ ) sin θ + ( cos 2 θ ) cos θ ( − 2 sin 2 θ ) cos θ − ( cos 2 θ ) sin θ d y d x | ( r , θ ) = − 2 sin 2 θ sin θ + cos 2 θ cos θ − 2 sin 2 θ cos θ − cos 2 θ sin θ (2) Substitute 1 for r and 0 for θ to obtain the slope of the curve at ( 1 , 0 ) . d y d x | ( 1 , 0 ) = − 2 sin [ 2 ( 0 ) ] sin ( 0 ) + cos [ 2 ( 0 ) ] cos ( 0 ) − 2 sin [ 2 ( 0 ) ] cos ( 0 ) − cos [ 2 ( 0 ) ] sin ( 0 ) = − 2 ( 0 ) ( 0 ) + ( 1 ) ( 1 ) − 2 ( 0 ) ( 1 ) − ( 1 ) ( 0 ) = 1 0 Therefore, the slope of the given curve at ( 1 , 0 ) is undefined

Angles in Circles

Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made p…

Arcs in Circles

A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
