Find all
solutions to the following equation on the interval 0 a 2π (in radians). 2 cos² (a) + cos(a) - 1 = 0 a = Give your answers as exact values in a list, with commas between your answers. Type "DNE" (Does Not Exist) if there are no
solutions. Do not use any trigonometric functions on a calculator or other technology, as they will not provide you with exact answers. Decimal approximations and answers given in degrees will be marked wrong.
