No. 05 Normal Probability Function Q(x)

Uses Hastings’ estimate formula to determine the probability of a standard normal distribution Q(x) illustrated below when the standardized variate (x) is known.

Q（x）

Q(x) =	1	∫	x	e−	t2	dt

	2 π
		0
(0 ≦ x < 1 ⋅ 1050)						x

Important!

Since this is an estimate formula, proper precision may not be obtainable.

No. 06 Coulomb’s Law

Determines the force (F) between two charges of quantities Q and q, over a separation of r.

F =	1	Qq	(r > 0) (Ƥ0: permittivity)

No. 07 Resistance of a Conductor

Determines resistance R of a conductor when its length () and cross sectional area (S), and the resistance of its component material ( ρ) are known.

No. 08	Magnetic Force

Units: : m, S: m2, ρ: Ω·m, R: Ω

Determines the motive force (F) in a conductor with electric current (I) flowing through it and placed in a magnetic field of uniform magnetic force density (B), when the length of the conductor is and the angle formed by the conductor and magnetic field is Ƨ.
