Question

find the gradient of the line y=x^(x^2) at point (2,16)

Answer 1

im getting 64 ln2 + 32 but that does not seem realistic

Answer 2

Thxx for your time Hero

Answer 3

yes

Answer 4

i have used the log rules and come up with the first entry on this quest but it seems unrealistic to me

Answer 5

yep got to that part so when i sub the point (2,16) it comes up with 16(4log(2)+2) which is approx 51. that sounds a lil too big

Answer 6

they also need an exact answ. using nat logs (ln) i get a diff answ from using plain logs. which method is the best

Answer 7

I got your answer too. x^(x^2) takes off like a rocket... a large slope is normal. Use natural logs. For some reason, Wolfram uses logs where most people use natural logs. I haven't researched why.

Answer 8

Juss handed in the assignment and i saw a foot note on Wolfram stating log (x) is the natural log i presume it's In. i used log

Answer 9

i wish i had seen the foot note earlier!!
