Hey everyone, it seems I cant get my head out of something as simple as a fraction operation. Last time I lost a test because of this so I MUST get this clear.
take this example which im working up now of a trigonometric function:
it's all good doing the derivative until the last 2 steps when you have to substract element 1 with 2 (highlighted in blue) and their denominators have common numbers/elements but not entirely similar one to another. I can't seem to find a way to end with the final result.
(The problem is always with functions that have roots. specially cubic root.)
