- 3\(sin45\,^{\circ}\)\(\frac{\sqrt{2}}{2}\)
- 4\(sin60\,^{\circ}\)\(\frac{\sqrt{3}}{2}\)
- 5\(sin90\,^{\circ}\)1
- 6\(cos0\,^{\circ}\)1
- 7\(cos30\,^{\circ}\)\(\frac{\sqrt{3}}{2}\)
- 8\(cos45\,^{\circ}\)\(\frac{\sqrt{2}}{2}\)
- 9\(cos60\,^{\circ}\)\(\frac{1}{2}\)
- 10\(cos90\,^{\circ}\)0
- 11\(tan0\,^{\circ}\)0
- 12\(tan30\,^{\circ}\)\(\frac{\sqrt{3}}{3}\)
- 13\(tan45\,^{\circ}\)1
- 14\(tan60\,^{\circ}\)\(\sqrt{3}\)
- 15\(a^m x a^n = ?\)Add the powers - \(a^m x a^n = a^{m+n}\)
- 16\(\frac{a^b}{a^c} = ?\)Minus the powers - \(\frac{a^b}{a^c} = a^{b-c}\)
- 17\((a^q)^p = ?\)Multiply the powers - \((a^q)^p = a^{qp}\)
- 18\(a^\frac{1}{2} = ?\)\(a^\frac{1}{2} =\sqrt{x}\)
- 19\(a^{-1} = ?\) \(a^{-2} = ?\) \(a^{-3} = ?\)\(a^{-1} = \frac{1}{a}\)
\(a^{-2} = \frac{1}{a^2}\)
\(a^{-3} = \frac{1}{a^3}\) - 20\(x^{-\frac{1}{2}} = ?\)\(x^{-\frac{1}{2}} = \frac{1}{x^{\frac{1}{2}}} = \frac{1}{\sqrt{x}}\)
- 210.4444... to a fraction0.4444... = x and 4.4444... = 10x
therefore 10x-x = 9x = 4
0.4444 ... = \(\frac{4}{9}\) - 220.4343... as a fraction0.4343... = x and 100x = 43.4343...
therefore 99x = 43 and
0.4343 = \(\frac{43}{99}\) - 235.2222... as a fraction5.2222... = 5 + 0.2222...
0.2222... = \(\frac{2}{9}\) + 5 =\(\frac{47}{9}\) - 24Formula for percentage changeoriginal price x multiplier = new
new price ÷ multiplier = original - 25Formula for compoound interestamount x multiplier\(^{no. of years}\)
- 26Formula for interior angle of a polygon(number of sides - 2) x 180 ÷ number of sides
- 27Formula for finding the gradient of a line\(Gradient = \frac{change in y}{change in x}\)
- 28Formula for the area of a sector\(\frac{\pi r^2}{360} x angle = area\)
