Remember that polar coordinates are about replacing x and y as coordinates for a point on a plane by instead r, r and theta,which is the angle measured counterclockwise from the positive x-axis.

极坐标是关于r，θ的,用r，θ代替平面上一点的x，y坐标，是从原点到那一点的距离，，which，is，the，distance，from，the，origin，to，a，point，θ是由x轴逆时针旋转,而得到的夹角。

It is the season for viewing Polar Mesospheric Clouds, and with our high beta-angle we were able to capture this thin layer of noctilucent clouds at sunset (6-25-2010).

到了观看极地中气层云的时候，在太空中使用高β角度，我们能捕捉到日落时刻这层薄薄的夜光云。

The angles refer to the polar view angle, i. e. the angle measured from the vertical.

角涉及到极面观的角，例如垂直物上测量的角。

If it's in polar form I passed in a radius and angle and I'll compute what the x- and y- value is.

以及半径和角度,但是现在是这样的,不管我是以哪种形式。
