Maths for a Cache #2 Mystery Cache

This cache has been archived.

inspicio: One or more of the following has occurred:

No response from the cache owner.
No cache to find or log to sign.
It has been more than 28 days since the last owner note.

As a result I am archiving this cache to keep from continually showing up in search lists and to prevent it from blocking other cache placements.

Should you like to resurrect the cache please create a new cache listing so it can be reviewed as a new cache.

4.23. Unarchiving a Geocache

The archiving of a geocache is intended to be a permanent status. That is why only community volunteer reviewers and Geocaching HQ staff have the capability to unarchive it. This is done only in rare circumstances and only if it meets the current Geocache Listing Guidelines.

If a geocache is archived by a reviewer or staff for lack of maintenance it will not be unarchived.

Geocache Description:

I hope you're good at maths... this is the next version of my Maths for a Cache series. This time, we're learning about derivatives!

Derivatives are a function that, when applied, gives the gradient at any point along the original function. For example:

f(x) = x3 + 4x2 - 3x + 8 ... the derivative (gradient function) is, f '(x) = 3x2 + 8x - 3


To find the final co-ords, all you have to do is work out the following questions that I have made up for you... S 24 51.ab3 E 152 23.x8y

 

Q1) To find a and y, find the derivative of: f(x) = 3x2 - 5x + 8

and find the gradient at x = 3/2

Q2) To find b and x, find the derivative of: f(x) = (2x + 5)3

and find the gradient at x = -2 ... ans. - 5

For extra brownie points, email me the derivative of: f(x) = (3x3 - 7)(3x3 - 7)
