Evaluate fraction numerator d over denominator d x end fraction open parentheses integral subscript 3 superscript x s e c (t )space tan (t )space d t close parentheses sec(x)tan(x) sec(x)tan(x) + C sec(x) - sec(3) sec(x)

  sec(x)tan(x)

Step-by-step explanation:

This is a direct application of the fundamental theorem of calculus, which tells you ...

Here, f(t) = sec(t)tan(t) and a=3. So, the derivative is ...

  f(x) = sec(x)tan(x)

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
