(20 14? Nanjing simulation) As shown in the figure, during the Spring Festival of 20 12, photographer S was in a park and found a column in front of B, measuring the top O of the column.

(1) As shown in the figure, we might as well record the photographer's eyes as point S and SC⊥OB as c.

According to the meaning ∠ CSB = 30, ∠ ASB = 60.

SA=3, so in Rt△SAB, we can get Ba = Satan 30 = 3.

That is, the horizontal distance from the photographer to the post is 3 meters ... (3 points)

From SC=3, ∠ CSO = 30, OC=SC in Rt△SCO? tan30 =3，

BC=SA=3, so OB=23, that is, the column height is 23 meters ... (6 points)

(2) As shown in the figure, with O as the origin and the horizontal direction to the right as the positive direction of the X axis, the plane rectangular coordinates are established.

Frame. Let M(cosα, sinα), α ∈ [0,2π],

Then N(-cosα, -sinα), and S(3,-3) from (I) ... (8 points).

So SM=(cosα-3, sinα+ has praise and tread. What's your comment on this answer?
