I need to find the vertical tangents for this function
I got this for the derivative
I know to set the denominator equal to zero and from there I'm stuck
Thanks in advance!
other than y = 0 , the other three zeros look to be irrational when graphed w/ a calculator. unless there's some clever trick, solving by hand may be rather messy.
