Caribbean Secondary Education Certificate Examination - Mathematics Paper

Flashcards based on key vocabulary and concepts from the Caribbean Secondary Education Certificate Mathematics Paper.

Barcode Area

The section in the examination booklet used for identification and tracking purposes.

Volume of a prism

$V = Ah$, where $A$ is the area of a cross-section and $h$ is the perpendicular length.

Volume of a cylinder

$V = ext{π}r^2h$, where $r$ is the radius of the base and $h$ is the perpendicular height.

Circumference of a circle

$C = 2 ext{π}r$, where $r$ is the radius of the circle.

Area of a circle

$A = ext{π}r^2$, where $r$ is the radius of the circle.

Roots of quadratic equations

If $ax^2 + bx + c = 0$, then $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$.

Sine rule

For triangle ABC, $\frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C}$.

Cosine rule

$a^2 = b^2 + c^2 - 2bc \cos A$ for any triangle.

Depreciation

The reduction in the value of an asset over time, in this case, 8% per year for a car.

Binary number

A number expressed in the base-2 numeral system, using only 0s and 1s.

Standard form

A way of writing numbers that are too big or too small in a compact format, using powers of ten.

Inequality
