Talk:Cauchy-Riemann Equations/Sufficient Condition

someone had wrote "It is not immediately apparent why $\cmod{\frac h t}\le1$ and $\cmod{\frac k t}\le1$ by Modulus Larger than Real Part and Imaginary Part". It's completely immediately: We know that $\cmod k\le\cmod t$ and $\cmod h\le\cmod t$, so by dividing we have $\cmod{\frac h t}\le1$ and $\cmod{\frac k t}\le1$.
