  • 1. Math.h <ul><li>Math.h is a header file declared before using basic mathemical operation such as </li></ul><ul><ul><li>Power (Squareroot, power) </li></ul></ul><ul><ul><li>Trigonometric(Sine, cosine, tangent) </li></ul></ul><ul><ul><li>Exponential and logarithmic (Log, exponential) </li></ul></ul><ul><ul><li>Rounding, Absolute value </li></ul></ul><ul><ul><li>Etc etc </li></ul></ul>
  • 2. Power <ul><li>Power </li></ul><ul><ul><li>Example : x^y should be written as power(x,y); </li></ul></ul><ul><ul><li>Example in coding: </li></ul></ul><ul><li>#include &lt;stdio.h&gt; </li></ul><ul><li>#include &lt;math.h&gt; </li></ul><ul><li>int main (){ </li></ul><ul><li>printf (&amp;quot;7 ^ 3 = %lfn&amp;quot;, pow (7,3)); </li></ul><ul><li>printf (&amp;quot;4.73 ^ 12 = %lfn&amp;quot;, pow (4.73,12)); </li></ul><ul><li>printf (&amp;quot;32.01 ^ 1.54 = %lfn&amp;quot;, pow (32.01,1.54)); </li></ul><ul><li>return 0; </li></ul><ul><li>} </li></ul>
  • 3. Power <ul><li>Squareroot </li></ul><ul><ul><li>Example : x^y should be written as power(x,y); </li></ul></ul><ul><ul><li>Example in coding: </li></ul></ul><ul><li>#include &lt;stdio.h&gt; </li></ul><ul><li>#include &lt;math.h&gt; </li></ul><ul><li>int main (){ </li></ul><ul><li>double param, result; </li></ul><ul><li>param = 1024.0; </li></ul><ul><li>result = sqrt (param); </li></ul><ul><li>printf (&amp;quot;sqrt(%lf) = %lfn&amp;quot;, param, result ); </li></ul><ul><li>return 0; </li></ul><ul><li>} </li></ul>
