如图,求x=cos^3(t)、y=sin^3(t)围成的面积.

如图,求x=cos^3(t)、y=sin^3(t)围成的面积. y=1-sin(2x)/sin(x)-cos(x)求T.最值 y =(cos^2) x - sin (3^x),求y' Sin x-sin y=2/3 cos x-cos y=1/2 求cos(x-y) 求导：x=cos^4*t,y=sin^4*t,求dy/dx 设x=e'sin t,y=e'cos t,求dy/dx. 参数方程:x=1+cosθ*t,y=sinθ*t,求普通方程, 求教各位数学大神：参数方程的定义域怎么求?如：x=a*(cos(t))^3,y=a*(sin(t))^3 (a>0),（积分求面积时用是我没说清楚，是求x=a*(cos(t))^3,y=a*(sin(t))^3 (a>0)围成的面积，要用定积分的话必须写出以t积分 设函数y=y(x)由参数方程x=cos t,y=sin t - t cos t确定,求dy/dx 当cos^2x-cos^2y=√3/2时,求sin(x+y）×sin(x-y) sin(x+y)sin(x-y)=k,求cos^2x-cos^2y 设x=a cos的3次方t y=a sin的3次方t求dy/dx 怎么求这个图形的面积 X=a cos^3*t Y=a sin^3*t matlab中怎么对下面的程序进行二维插值并画出三维视图呢?[x,y]=meshgrid(-2:1:2);t=2;Z=[(sin(t))^3 t^2 sin(t) cos(t) (sin(t))^2;t^2 sin(t) (cos(t))^4 cos(t) (sin(t))^2;t sin(t) cos(t) t^2 (sin(t))^2;sin(t) (cos(t))^3 t^2 (sin(t))^2 y=sin(x/2)-cos(x/2)求周期T? 已知 x = e^t * cos t y = e^t *sin t 求当t= π/3时dy/dx的值 求 y=cos t/(1-sin t)的导数 1/1-sin t 求y=sin＾2(x)+3sin(x)cos(x)-2cos＾2(x)的最大值
