Symbols of Maths, Physics and chemistry in text message for WAEC and NECO Exam

 These are the symbols we use in solving some mathematical solution in the following subjects, like: Physics, Chemistry, Mathematics and others. So, these symbols are very very important to you. Because we dont need/want a situation whereby we would solved the solution that will confused you. And you ending up lumping down things you dnt know of... Due to lack of symbolic login, you will end you failing your important subjects (but God forbid). And you will start blaming onLuckytech. So dont just with these symbols, Please!!

Tables, Radiativity Diagrams

Table1
A table of this would be computer as follows
X:1,2,3,4
FX:4,6,8,10
F(X-Xbar):10,8,6,4


Table2
A table like this would be computed as follows
Particulars: maintenance,salaries &wages, Purchase of Drugs, total
Amount: 2500,1000,2000,5500


Logarithm Table

Tabulate
No:92.63, Log:1.9667
No: 2.914, Log: 0.4645
2.4312
Antilog = 269.9
Therefore 92.63*2.914=2.4312


Radiativity Diagram

means
(238)U(92)=>(234)Th(90) + (4)He(2)

This is computed as follows
(1)(-b± sqr rut(b^2-4ac))/2a
(2)Sqr root ((2Qh)/100)
(3)Xbar=Efx/ef
(4)Summation (n=1 to infinity )P(n)
(5)S.D= Sqr Rut ((Ef|x-xbar|^2))/Ef
(6)R is proportional to1/ sqr rut
