Circles formula

Diameter = 2 x radius of circle.

Circumference of Circle = PI x diameter = 2 PI x radius
where PI = = 3.141592...

Area of Circle:
area = PI r²

Tables of Integrals

Power of x.

xn dx = xn+1 (n+1)-1 + C (n -1)

x-1 dx = ln|x| + C

Exponential / Logarithmic

ex dx = ex + C	bx dx = bx / ln(b) + C
ln(x) dx = x ln(x) - x + C

Differentiation Rules =)

Happy learning with all this rules! =)
Eventhough most of this formula is given in your examination.. I hope all of us can memorize this rules so that we can answer the question quickly without wasting our time to check the formula. yehaaa!
Math is FUN!
