Magnetic Flux Density at different points about a solenoid

1. Homework Statement
For my physics investigation I am required to first find the theoretical magnetic flux denisty at different points about a solenoid. The points are outside the solenoid: along the axis but past the ends and; perpendicular to the centre of the solenoid but outside.

So far I have looked at many links to Biot-Savart law, but they only seem to show equations for a loop and not a solenoid.

2. Homework Equations
I have tried for the point along the axis:

but it only works with in the confines of the solenoid.

I also tried:

but it doesn't work for the solenoid.

What I basically need is two equations, one for the axis, and, one for the points perpendicular to the centre.
