The Equation for calculating angle thi (I am not quite sure how spell it) has a a denominator of 2 multiplied by SQRT of (-a^3)/27. When the value of a is positive, this equation will result in a SQRT of a negative number. How can one calculate this angel in this case? Thank you

these are really priceless coaching >>>

but can anyone say mi any video related to stress tensor problems in this nptel >>

i require it very much it s not found in any books too
