Antenna Gain Pattern:
The gain G of a certain microwave dish antenna can be expressed as a function of angle by the equation:
G(θ)= |sinc 4θ| for –π/2 ≤ θ ≤ π/2
Where θ is measured in radians from the boresite of the dish, and sinc x = sin(x)/x. Plot this gain function on a polar plot, with the title "Antenna Gain vs θ" in boldface.

The answer above is correct its: Draw a ray with one end point

Step-by-step explanation:

An instructor is shown in front of a whiteboard. The instructor uses the following steps to copy an angle.

You are given an angle.

Draw a ray with one endpoint. This endpoint will be the vertex of the new angle.

Place the compass on the vertex of the given angle, and swing an arc that intersects both rays of the given angle.

Place the compass on the vertex of the new angle, and swing an arc similar to the first one you created.

Open the compass to the width of the intersection points of the rays and arc of the given angle.

Place the compass on the intersection point of the ray and arc of the new angle, and swing another arc that intersects the first.

Draw a ray through the new vertex and the intersection point of the two rays.

This second ray creates an angle that is congruent to the given one.

An instructor is shown in front of a whiteboard. The instructor uses the following steps to bisect a segment.

You are given a segment with two endpoints.

Place the compass on one of the endpoints and open the compass to a distance more than halfway across the segment.

Swing an arc on either side of the segment.

Keeping the compass at the same width, place the compass on the other endpoint and swing arcs on either side so that they intersect the first two arcs created.

Mark the intersection points of the arcs and draw a line through those two points.

The point where this new line crosses the given segment is the midpoint and divides the segment in half.
