क्या खुब लिखा है गुलजार जी ने ...

पानी से तस्वीर

            कहा बनती है,

ख्वाबों से तकदीर

            कहा बनती है,

किसी भी रिश्ते को

            सच्चे दिल से निभाओ,

ये जिंदगी फिर

            वापस कहा मिलती है

कौन किस से

            चाहकर दूर होता है,

हर कोई अपने

           हालातों से मजबूर होता है,

हम तो बस

            इतना जानते हैं...

हर रिश्ता "मोती" और

            हर दोस्त "कोहिनूर" होता  है।

🌹💞 Keep Smiling ☺ 💞🌹

बिना शादी के ही जिंदगी में इतनी

काँव-काँव हैं

तो शादी के बाद कितनी होगी..

After doing BCA which subject is highly demand in government teacher job...math or computer

After doing BCA which subject is highly demand in government teacher job...math or computer

Aiming for a teaching career in government schools you will have to qualify the exam conducted by government like Teachers Eligibility Test (TET), TGT, PRT, PGT and so on.

For example:

TET will have two papers with multiple-choice questions-
*Paper I will be for those intending to become teachers for classes I-V.
*Paper II will be for those aspiring to teach between classes VI and VIII.
Those interested in teaching from Class I to VIII will have to appear for both papers.
The TET is conducted both by the central and state governments of India. Most states conduct their own TET.
Eligibility Criteria:
People with professional teaching qualifications, including the B.T.C (D.El.Ed), B.Ed, and B.El.Ed, are eligible to take the test.
Candidates must score over 60% to pass.

Teaching is a very good profession  in India.
So , after doing BCA you have choice in computer as for maths you require graduation in B.Sc. Maths for government teacher and also B.Ed. is essential for government teacher job.  

Sphere formula in maths

Sphere formula:


A three-dimensional figure with all of its points equidistant from its center. Radius: r Diameter: d Surface area: S
 Volume: V
 S = 4 Pi r² = Pi d²
 V = (4 Pi/3)r³ = (Pi/6)d³

---

---

Sector of a Sphere
 The part of a sphere between two right circular cones that have a common vertex at the center of the sphere, and a common axis. (The interior cone may have a base with zero radius.)
 Radius: r
 Height: h
 Volume: V
 S = 2 Pi rh
 V = (2 Pi/3)r²h

---

Spherical Cap
 The portion of a sphere cut off by a plane. If the height, the radius of the sphere, and the radius of the base are equal: h = r (= r₁), the figure is called a hemisphere.
 Radius of sphere: r
 Radius of base: r₁
 Height: h
 Surface area: S
 Volume: V
 r = (h² +r₁²)/(2h)
 S = 2 Pi rh
 V = (Pi/6)(3r₁²+h²)h

---

---

 Segment and Zone of a Sphere
 Segment: the portion of a sphere cut off by two parallel planes.
 Zone: the curved surface of a spherical segment.
 Radius of sphere: r
 Radii of bases: r₁, r₂
 Height: h
 Surface area: S
Volume: V
 S = 2 Pi rh
 V = (Pi/6)(3r₁²+3r₂²+h²)h

---

---

Lune of a Sphere
 The curved surface of the intersection of two hemispheres.
 Radius: r
 Central dihedral angle: theta (in radians), alpha (in degrees)
 Surface area: S

 Volume enclosed by the lune and the two planes: V

 S = 2r²theta = (Pi/90)r²alpha

 V = (2/3)r³theta = (Pi/270)r³alpha
