peaches怎么读是读/pi:t∫is/还是/pi:t∫s/?后面读is还是直接加s？ sin(pi*t)/(pi*t)怎么用matlab实现 pi:t∫的单词 The monkey is eating peaches改成一般现在时 Let is have some peaches ard pears 高中数学f(t)=1+Cos(2000*Pi*t)+Sin(4000*Pi*t)f(t)=1+Cos(2000*Pi*t)+Sin(4000*Pi*t) Pi为3.1415926 f(t)的频率【或周期】怎么求啊 ∫(e^(t^2))dt=根号pi 怎么证明出来的啊? peaches are my favourite fruit.=my favourite fruit are peaches.还是my favourite fruit is peaches? Do you like peaches 怎么回答 设f(x)=∫((pi,x) sintdt/t,求∫(0,pi) f(x)dxf'(x)=sinx/x,f(pi)=0 这么个解释,怎么得出的? matlab 新手 Conversion to double from sym is not possible.syms ty=3*0.02*exp(-5*t)+exp(-12*t)-4*exp(-4*t)*sin(3*t+pi/6)plot(t,y)怎么画不出来图? I don't like ( ) A.peach b.peaches c .orange pi( )t( )( )e 填空 一道高数三角函数问题-0.16sin(10t+pi/4)怎么变成0.16sin(10t-pi/4)求变化过程.写错了，-0.16sin(10t+pi/4) 0.16sin(10t-3pi/4) w=sin(t),b=2cos(t),z=t,t从-2pi到2pi,用Matlab怎么画(w,b,t)的图像 the monkey is eaing peaches 改为一般疑问句 matlab如何构造一个含变量的矩阵比如有一个矩阵T=[cosa,-sinacosb,sinasinb;sina,cosacosb,-cosasinb;0,sinb,cosb]里面的a=0:pi/36;pi;b=0:pi/36;pi;怎么去构造这个T矩阵呢?打错了,应该是a=0:pi/36:pi;b=0:pi/36:pi I like apples.I don't like peaches.(两句合并一句） I like apples___ ___ peaches.越快越好
