已知函数y=1/2sin【（x+π）/A】（A>0）的最小正周期为3π,则A= 函数y=2sin²x-1的最小正周期为? 请问GAY是什么意思`` 对应用统计学的看法越详细越好..字数不限... 我永远爱你的英文怎么拼写 函数y=根号2sin(x/2+π/3)的最小正周期是 函数y=√2sin(x/2+兀/3)的最小正周期是 请问,gay是什么意思? The weather in China is different from;____ in Australia.The weather in China is different from ­­____ in Australia.A it b THAT c one d ones可是为什么A不可以? 已知函数y=1-2sin(ωx-π/3)(ω>0)的最小正周期是4(1)求函数的最值及取的最值时自变量x的取值集合(2)求函数的单调区间 the weather in Australia is different from (China/in China)哪一个正确 the weather different that in china in Australia from is China is different from Australia ___weather 怎么做啊 1对1提问有好处吗? The weather in China is _____ in Australia .A_different form B_different form that C_that same as D_the same as that 化石吟第一节不断提问有什么作用 求详解 .若函数fx=x-4 /mx²+4mx+3的定义域为R,求实数m的范围 已知函数y=√mx²-6mx+m+8的定义域是R,求实数m的取值范围.我知道答案,y=√(mx²-6mx+m+8)的定义域是R∴mx²-6mx+m+8≥0恒成立m=0不等式即8≥0,符合题意m≠0时,不等式为二次不等式,恒成立的条 Meimei had a busy day yesterday.She g_ up before seven o'clock in the morning,and quick w_ her hands and face.She got to school e_.She h_ a little rest after lunch,but she worked home.Her pen was broken,so she n_a new one .On her way she b_a new pen 函数y=2sin(2x-π/6) 的最小正周期是? 函数y =2sin(1/2·x+派/6 )的最小正周期是? 画出函数y=5/2sin(x/2+π/6)在一个周期内的图像,并求出这个函数的振幅，周期，频率，相位，初相 求符号2-8题 8 8 8 8 ＝2 填什么符号? 从2到8 怎样变符号是零 加上合适的运算符号和括号：8 8 8 8 8 8 8 8 8=2如题 1.Shanghai is in the e____of China2.The ball is 200 yuan.It is d_____.
