已知集合M={X/X=mπ+π/6,m∈Z}N={X/x=(nπ)/2-π/3,n∈z}p={x/x=(pπ)/2+π/6,p∈Z}则M,N,p的关系是
已知集合M={X/X=mπ+π/6,m∈Z}
N={X/x=(nπ)/2-π/3,n∈z}
p={x/x=(pπ)/2+π/6,p∈Z}则M,N,p的关系是

已知集合M={X/X=mπ+π/6,m∈Z}N={X/x=(nπ)/2-π/3,n∈z}p={x/x=(pπ)/2+π/6,p∈Z}则M,N,p的关系是
M={X/X=mπ+π/6,m∈Z}={.,-5π/6,π/6,7π/6,13π/6,.}
N={X/x=(nπ)/2-π/3,n∈z}={ ...,-5π/6,-2π/6,π/6,4π/6,7π/6,10π/6,13π/6,.}
p={x/x=(pπ)/2+π/6,p∈Z}={.-5π/6,-2π/6,π/6,4π/6,7π/6,10π/6,13π/6,.}
∴M真包含于N=P
