An online calculator and solver for tangent equations of the form \( \tan(x) = a \) is presented.
The Equations has the form \[ \tan(x) = a \]
whose solution is given by
\( x = \arctan(x) \)
The solutions are given in radians and degrees.
The \( \tan(x) = a \) equation has an infinite number of solutions. Hence, the calculator gives the solution in the intervals: \( (-\dfrac{\pi}{2} , \dfrac{\pi}{2} ) \) and \( (-90^{\circ} , 90^{\circ} ) \) and then add a multiple of \( \pi \) and \( 180^{\circ} \)

Use the calculator to solve the equation \( \tan(x) = a \) for \( x \)

Enter \( a \), as a real number, and press "enter".
