title: calculate the angle between 0 and 90 with adding 15
body: <p>I write this code to get sin of angles between 0 and 90</p>
  
  <p>example:</p>
  
  <pre><code>1: sin(0) =
  2: sin(15)=  
  ....
  7: sin(90)=...
  </code></pre>
  
  <p>So I have written this code but he show me only one result
  where is my problem ?</p>
  
  <pre><code>#include &lt;stdio.h&gt;
  #include &lt;stdlib.h&gt;
  #include &lt;conio.h&gt;
  #include &lt;math.h&gt;
  #include &lt;time.h&gt;
  
  int main()
  {
      int i;
      float x;
  
      for (i=0;i&gt;90;i=i+15);
      {
          x = sin(i);
          printf("sin(%d)= %f\n", i, x);
      }
      getch();
      return 0;
  }
  </code></pre>
