Whether it is by way of adjusting the chromatophores underneath the skin or producing a whole new coat of outer covering to match the seasonal colours, most camouflage involve animals mimicking the look of the i

## Diodes and Solar Panels

Diodes & Solar Panels [S3/S4 Physics & Chemistry: Electricity / Covalent Bonds] The greatest dilemma of modern energy generation confronts the serious problem of trying to make renewable energy substitute what limited fossil fuels we still have left on Earth. As such, it is imperative to understand circuitry and how it may be used in everyday lives. With the copious amount of rain and sun Singapore experiences, many might think of solar panels and hydro-electric alternatives

## Re: "I don't understand the Quadratic / Cubic Formula."

[S2 - A Level Mathematics: Functions & Graphs] (Long Video. If you feel like you don't understand graphs, this is worth a watch) You might be used to the Quadratic Formula if you're familiar with the Secondary School Maths curriculum. It's a very simple equation that spits out the answers you want as long as you put the coefficients in the right parts of the equation. It's also one of the first times you were given a mathematical formula featuring such complex algebraic arran
