If you want even more functionality of Kcalc there is also scientific mode which is acessed from :menuselection:`settings --> scientific mode` radio button. The button :guilabel:`1/x` takes takes 1 and divides it by the number currently on the calculator also known as taking the reciprocal. :guilabel:`x!` read x factorial will take the number X you entered and multiple each number going down to 1 for example 5! would multiply 5*4*3*2*1.
The x squared button will take a x*x and multiply it by itself. The button with x and a superscript y will take x the number you have in will exponeniate x to the power of y. The x 10 with a supercript y will end up multiplying x by 10 to the power of y so for example to multiply 5 by 10 to the power of 3 entering in will give the answer of 5,000.

To change the unit that angles are measured in for triginometric units in Kcalc. Degrees take 360 to form a full circle while, 2Π radians form a full circle and 400 gradians form a full circle. The radio button for Deg is to select Degrees as the unit for angles, Rad selects :guilabel:`radian` as the unit of measurment of angles and :guilabel:`Grad` selects Gradians as the unit of measurement for angles. The :guilabel:`Sin` button takes what you have as the input and takes the trigonometric sine function of that value measured in the unit for angles you have selected. The :guilabel:`cos` button takes the cosine of the vlaue in the unit of angle you have selected. The :guilabel:`tan` button takes the tangent of the angle in the current units.
