After putting in the initial values and a bit more work, the following formula can be derived: Fn=⌊ϕn5+12⌋.Fn=⌊5ϕn+21⌋. This can immediately be used to calculate FnFn : from __future__ import division import math def fib(n): SQRT5 = math.sqrt(5) PHI = (SQRT5 ...
Tocalculate the inductance of a solenoid, the following formula can be used: {eq}L = \frac{{\mu}N^{2} A}{l} {/eq} Where {eq}\mu {/eq} is the permeability of free space with a value of {eq}4\pi \times 10^{-7} \ T m/A {/eq}, N is the number of loops, A is th...

You have to do something like Divide & Conquer optimization. Consider that you now need to precalc something for the interval [L;R] You should take and calculate answers for queries [M;M], [M;M + 1], ..., [M;R] Calculate same thing for queries [M - 1;M - 1]...
How to calculate the lighting needs of a space? How to measure light efficacy? How to calculate the distance of light? How to measure lux levels? How to calculate lumens per watt? And so on… Why do you need to know all this information?
Step 2 - Calculate countThe COUNTIF function calculates the number of cells that is equal to a condition. Function syntax: COUNTIF(range, criteria)COUNTIF($B$3:B3,B3)returns 1Step 3 - Add count to rankRANK.EQ(B3,$B$3:$B$9,1)+COUNTIF($B$3:B3,B3)...

The phase constant tells you how displaced a mathematical wave is from an equilibrium or zero position. You can calculate it as the change in phase per unit length for a standing wave in any direction. You can use it to calculate how many oscillations a
The COUNTIF function calculates the number of cells that meet a given condition. The image above shows names in cell range B3:B10, the formula in cell D3 counts the cells in B3:B10 equal to a specified condition. The condition in this example is "Lucy". Formula in cell D3: =COUNTIF...
In contexts like public health, rare events such as cancer or maternal mortality assume a Poisson distribution, which we can use to calculate confidence intervals used to compare rates. For more, see this handout from the Utah Department of Health and Human Services: This distribution is not sy...
