The number π (/paɪ/; spelled out as "pi") is a mathematical constant that is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159. The number π appears in many formulae across mathematics and physics. It is an irrational number, meaning that it canno...
Physically, this ring is interpreted as the superposition of all the plane waves in the McCutchen sphere whose wavevectors of modulus k lie on a conical surface of angle [[theta].sub.0] = arctan ([k.sub.t]/[k.sub.z]) with respect to z axis and satisfying [k.sup.2] = [k.sup...

tangent(x) is equivalent totan(x) except that it also works on sparse arrays. The optional argument null (default, (-numpy.inf, numpy.inf)) may be specified to indicate what value(s) should be assigned when x == -pi/2 or -pi/2. If only one number is given, then it is used f...
The paper is structured as follows. Section 2 presents what we called the projection algorithms, a family of dual algorithms for solving the projection problem (4). Then Section 3 deals with the Slater condition, which has a geometric appeal in our context in addition to its role in the ...
The set of complex numbers at which exp z is equal to one is then an (imaginary) arithmetic progression of the form: displaystyledots,-2pii,0,2pii,4pii,dots=2pikimidkinmathbbZ and there is a unique positive real number π with this property. A variation on the same idea, making us...

If x is AM of tan[π/9] & tan[5π/18] & y is AM of tan[π/9] & tan(7π/18. What is the relation bw x & y? https://math.stackexchange.com/q/2355181 Logically y>x, because tan70>tan50, hence the choice y=2x is right. Proof: x=2tan20+tan50=2cos20cos50sin(20+50...
