Just put the expression in double quotes, like this:</p> <pre class="terminal">~> DeskCalc "sin(45)*(cos(12)+3.45)" 3.65365546732025461817951947270058</pre> <p>Note: Used in the Terminal, DeskCalc will always use radians as unit for these trigonometric functions.</p></li> </ul> </div> </div> <div class="nav"> <div class="inner"><span> « <a href="codycam.html">CodyCam</a> :: <a href="../applications.html#list-of-apps" class="uplink">Applications</a> :: <a href="diskprobe.html">DiskProbe</a> » </span></div> </div> </body> </html>
