As earlier mentioned on this blog, and as we have promised all our prospective candidates for 2017 WAEC runs,we have finally compiled all the signs and symbols that will help you in Mathematics,Physics and Chemistry and we have also interpreted them the way it will be easy for you to understand while writing WAEC , so that you wont go to the hall and start messing up,thereby wasting the efforts we have made towards giving you the best to make sure that you smash A's in 2017 WAEC. So, listed and explained below are the signs and symbols as they will appear in our 2017 waec runs.Please, start now to study and memorize them.It will help you alot. ●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●● ●●● (1) / means division or divide Examples: 2/2 means 2/2 2 whole no 3/4 means 2¾ M=wp+(1/3)yp^2 means m=wp + ¾y 2 (2) Log means logarithm Example: (8) Log5 (base 8) means Log8 5 (3) * means multiplication Example: 2*2 means 2×2 (4) ^ means Raise to power Examples: 3^(-1) means 3 -1 5^(2) means 5 2 30cm^(-2) means 30cm -2 (5) Tita means θ Example: Tan tita means tan θ (6) Pie means π Example: Pie R sqr h means πr 2 h (7) Base means subscript Example: 2 Base 3 means A 3 (8) Sqr root means √ Examples: √3-√6+2√3 means Root 3-root6+2root 3 √(¾) means sqr root(3/4) (9) bar means a dash on top a number of letter Example: X bar means x̅ (10) —(1) means equation 1 (11) Proportional means ∝ Example: R is proportional to 3/4rut m means R ∝ ¾ (12) Alpha means α (13) Beta means β (14) Gamma means γ (15) cube root means ∛ (16) Mu means μ (17) Rho means ρ (18) Delta means δ (19) Sigma means σ (20) Tau means τ (21) Ohm means Ω (22) Lamda means λ (23) Omega means ω (24) Intersection means ∩ Example: B intersection C means B∩C (25) Union means U Example: B union C means BUC (26) Factorial means ! (27) complements in sets means ‘ (28) (aq),(g),(l),(s) is used in chemistry to show the state of matter in equations (29) Equivalent to means ≡ (30) Not equal to means ≠ get free expo @ bmasterz.c☆com (31) Quotation means “ ” (32) Less or equal to means ≤ (33) Greater or equal to ≥ get free expo @ bmasterz.com Example: (3/4)>=(1/2) means ¾ ≥ ½ (34) Plus or minus (or +-) means ± Example: (3/4)<=(1/2) means ¾ ≤ ½ get free expo @ bmasterz.com (35) Element of means ∈ Example: 2 belongs to X or 2 is a member of X means 2∈X (36) Percent or percentage means % (37) Degrees Fahrenheit means ℉ (38) Degrees Celsius means ℃ (39) Universal set means ξ or U (40) Null or empty set means ∅ or {} (41) (42) 2.S.F means 2 significant figures (43) P=(2,3) means P={2,3} in sets (44) Propotional to means ∝ (45) Therefore means ∴ (46) KNO(3)(s) means KNO3 (s) (47) NaCl=> Na^(+) + Cl^(-) means NaCl → Na+ + Cl- get free expo @ bmasterz.com (48) Summation means Ʃ (49) Parallel lines means ǁ (50) Perpendicular lines means ˩ (51) Reversible equation means ↔ (52) Infinity means ∞ (53) Approximately means ~ (57) Approximately equal to ≅ Other Symbols (1) File means ɸ (2) Δ means Change or Triangle (3) slope or differentiation means dy/dx or ∂y/ ∂x or δy/δx or Δy/Δx (4) Parenthesis means … (5) Naira means ₦ (6) Integral means ∫ get free expo @ bmasterz.com (7) Almost equal to means ≈ (8) For all means ∀ (9) There exist means ∃ (10) Epsilon means ε (11) Vertical dots means ⁞ 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 get free expo @ bmasterz.com 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 root ●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●●● ●●●
