Trigonometric Table(Sin, Cos, Tan, Cosec, Sec & Cot) From Angle 0 to 360 Degree In this post I have provided all the values of trigonometric ratios (sin, cos, tan, cosec, sec & cot) from angle 0 to 360 degree. These specific values of angle(0 to 360 degree) is very important for all the students because

Below are the list of all important algebraic formulas. 1. (a+b)² = a²+b²+2ab 2. (a-b)² = a²+b²-2ab 3. a²-b² = (a-b)(a+b) 4. (a+b)³= a³+b³+3ab(a+b) 5. (a-b)³= a³-b³-3ab(a-b) 6. a³+b³ = (a+b)(a²+b²-ab) 7. a³-b³ = (a-b)(a²+b²+ab) 8. (a+b+c)² = a²+b²+c²+2ab+2bc+2ca 9. a³+b³+c³-3abc = (a+b+c)(a²+b²+c²-ab-bc-ca)

There are many important formulas of laws of exponent but one of the most important formulas of laws of exponent are as under- 1. a⁰ = 1 2. (am)n = amn 3. am × an = am+n 4. am ÷ an = am–n 5. am × bm = (ab)m 6. am ÷ bm = (a÷b)m 7. 1÷a⁻¹ = a

If any students want to know roman numbers from 1 to 1000 then learn only bellow roman number. 1 I 2 II 3 III 4 IV 5 V 6 VI 7 VII 8 VIII 9 IX 10 X 11 XI 12 XII 13 XIII 14 XIV 15 XV 16 XVI 17 XVII 18 XVIII 19
