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

Secret of extremely long life
“Keep a quiet heart, sit like a tortoise, walk sprightly like a pigeon and sleep like a dog .”
Secret of extremely long life
COVID-19
No matter who you are or what you do, right now you should be focused on your health - and not about whether you will lose your job or run out of money for things like groceries or medicine.
The spread of COVID-19 is forcing all of us to change our ways, and we know it’s a big adjustment. But we will fight, and together we will get through this by taking precautions.
It is practically impossible to completely prevent the spread but you can take certain measures to reduce the chances of getting it.
Wash your hands often – It is probably the best measure to prevent the transfer of cold or any kind of infection. Use sanitizer while being in any public places and also make it a point to wash hands before eating. Teach the importance of hand-wash to kids also.
Avoid touching your face – Try not to touch face, mouth, nose & eye areas, when you are near to a person infected with cold.
Control stress – People facing emotional stress regularly have a weaker immune system, which implies that they could catch a cold easily. So, reduce stress and live a healthy life.
Cleanliness – Keep household surfaces like doorknobs, drawer pulls, keyboards, light switches, telephones, remote controls, countertops, and sinks clean. These are the places where viruses lie for hours after they are used by an infected person.
Avoid Smoking – Cigarette smoke could raise the chances of susceptibility to colds and other infections. Avoid passive smoking as well.
Drink sufficient amount of water – Drink water, juice, warm lemon water and other warm fluids. These will help you to stay away from it.
