the trip was ______(please)变换填空

鬼蚂蚁1年前4

小猪丫丫6 共回答了15个问题 | 采纳率93.3%

The trip was __pleasant.____(please)
was 是连系动词,后面需要形容词pleasant“令人愉快的”作表语.
pleasing是令人高兴/开心/愉快的,讨人喜欢的,有点主动的含义.与pleasant和pleased不同.
pleasant和pleased都有“高兴的”意思.pleasant所形容的物或人常给人们带来愉快或欢乐.pleasant通常与news,day,weather,voice,view,trip 等名词连用.
pleased指对某人或某事感到高兴或满意,含有被动之意,用于修饰人,其后常与with,about或动词不定式连用,有时也可接从句.

若sina+sinb=((√3)/3)(cosb-cosa),a,b∈(0,∏),则a-b=      

wangxinxinxo1年前1

老_公 共回答了21个问题 | 采纳率100%

这道题目很新颖,不错的题目.
3sina+根号3*cosa+3sinb-根号3*cosb=0
则有2*根号3*sin（a+30）+2*根号3*sin(b-30)=0
则有sin（a+30）+sin（b-30）=0
a,b∈(0,∏)
所以可能的情况就是a》150时,a+30》180,而另外b》30,这样b-30》0
即当a》150,b-30》0时
从而刚好使得a+30与b-30在一条直线上,即有a+30=180+b-30
则a-b=120度
其他的可能性不存在.

关于高中函数伸缩变换,对称变换,翻转变换

关于高中函数伸缩变换,对称变换,翻转变换
为什么y=f(kx)（k＞0）与y=f(x)的图像的纵坐标不变,横坐标变为原来的1/k倍（k＞1时缩短,0＜k＜1时伸长
2为什么y=f(x)与y=f-(x)的图像关于y轴对称
3为什么y=f(x)与y=-f(x)的图像关于x轴对称
4为什么y=f(x)与y=-f(-x)的图像关于原点对称

hncyq1年前2

01083114 共回答了19个问题 | 采纳率89.5%

思路可以通过两个图像的点之间的对应来考虑
1. 设(x0,y0)是y=f(x)上的点,那么相应的(x0/k,y0)就是y=f(kx)上的点,这就是纵坐标不变,横坐标变为原来的1/k
2. 设(x0,y0)是y=f(x)上的点,那么相应的(-x0,y0)就是y=f(-x)上的点,纵坐标不变,横坐标变为相反数,这就是关于y轴做了对称变换
3. 设 (x0,y0)是y=f(x)上的点,那么相应的(x0,-y0)就是y=-f(x)上的点,横坐标不变,纵坐标变为相反数,这就是关于x轴做了对称变换
4. 设(x0,y0)是 y=f(x)上的点,那么相应的(-x0,-y0)就是y=-f(-x)上的点,横坐标和纵坐标均变为相反数,这就是关于原点做了对称变换

y=sinx怎样变换得到y=-sinx

由于y=-sinx =sin[x +(2k+1)π],
故只要将函数y=sinx的图像向左或向右移动(2k+1)π个单位,即可得到y=-sinx
其中,k为整数

改一般疑问句很简单,有be动词的话只要把be动词（be动词一般为：is,are,was were.）提前就好了.如果没有be动词的话就自己加助动词（助动词为：do ,did ,does）加在句首,如果是过去式记得did后面加原型,不要忘了变.一般的考点都是在这里.
对划线句子提问的话,就是根据要提问的东西相对应的写出.例如：时间就是when,个数的话就是how many.等等
同义词的话就是背相等的短语.这是要死记硬背的哦.
连词成句的话就看自己平时的训练了.像这一道题的话,有疑问词的话就放在开头,没有的话就是主语,然后就是be动词了,最后就是要靠事件的发展了（这是自己平常训练的）.
