Revision 5.
</p>
<p>Directly computes derivatives from ordinary Python functions using auto differentiation. The technique directly computes the desired derivatives to full precision without resorting to symbolic math and without making estimates bases on numerical methods.</p>
<p>The module provides a Num class for "dual" numbers that performs both regular floating point math on a value and its derivative at the same time. In addition, the module provides drop-in substitutes for most of the functions in the math module. There are also tools for partial derivatives, directional derivatives, gradients of scalar fields, and the curl and divergence of vector fields.</p>

</p>
<p>EMI Calculator is used to calculate Equated Monthly Installment(EMI) for Home Loans/Housing Loans,Car Loans & Personal
Advantages: What all this EMI Calculator does?</p>
<p>. The Instant calculation of Loan EMI , Total Interest Payable and Total Payments to be done.
. This can be used as EMI Calculator for Banks like HDFC, ICICI, SBI, AXIS etc.
. This can be also used for calculating Home loans, Personal Loan, car loans , credit card, LIC loan</p>
<p>How to calculate the EMI?</p>
<p>The well known formula for calculating EMI is:</p>
<p>Formula for EMI calculation</p>
<p>[Formula]
EMI = [(p*r/12) (1+r/12)^n]/[(1+r/12)^n – 1 ]
where p = principal amount(primary loan amount)
r = rate of interest per year
n = Total number of Years</p>
<p>output:</p>

<p>This program takes input from the user and determines the amount of gardening materials needed for a garden. The garden is a perfect square. The four outer flowerbeds are congruent semicircles and the central flowerbed is a perfect circle. Everything else inside the garden is considered fill: stone, mulch, or other fill material.</p>

Revision 2.
</p>
<p>FreshFish is a function decorator for functions with no arguments (hardware query).</p>
<p>The first time the function is called, the wrapper caches the result (the fish). Subsequent calls to the wrapped function simply return the cached result as long as the fish is still fresh. When the fish goes stale, FreshFish calls the underlying function again for FreshFish.</p>
<p>I used this on a BeagleBone project to monitor heart rate, speed, and cadence.</p>
