    Study Notes

    Mathematics

    • In an isosceles right triangle, (2\sin A \cos A = \sin(2A)) leading to various options.
    • Average calculations involving sums; average of 17 numbers is derived from calculated values of subsets.
    • Understanding the relationship between mean and the total number of observations for problem-solving.

    Physics

    • Analyzing efficiency of machines: efficiency = (output work / input work) x 100%.
    • Concepts of kinetic energy calculated using mass and height: KE = (mgh).
    • Exploring properties of electric lines: they exist around electric charges and describe force fields.

    Chemistry

    • Recognition of reducing agents in reactions; elements like Calcium are common reducing agents.
    • Oxidation numbers are critical for identifying the state of elements in compounds, such as sulphur in H2SO4.

    General Knowledge

    • Global trade is majorly served by shipping.
    • Understanding currency: 'Ruble' is associated with Russia.
    • The Panama Canal is a significant geographical feature that connects the Pacific and Atlantic Oceans.

    Algebra

    • Solving equations to find the multiplicative inverse and other values in algebraic expressions.
    • Techniques for calculating area and volume from given face areas in solids.
    • Ratio problems requiring understanding of proportions and percentages.

    Geometry

    • Angle relationships in geometry involving circles and triangle properties.
    • Pythagorean theorem applications in right triangles for angle calculations.

    Environmental Science

    • Identify pollution as a significant threat to waterways and oceans; it's essential to understand the impact of human activities.

    Biology

    • Life cycle stages illustrated through examples; for instance, tadpole to frog analogies.
    • Understanding food sources and livestock classifications related to agriculture.

    Geography

    • Recognizing major islands and countries; distinguishing Japan's islands from others.
    • GPS ownership and its implications for navigation technologies.

    Problem Solving Techniques

    • Approaching problems methodically, using logical reasoning to deduce relationships and outcomes (e.g., positions in rankings, distance-time problems).
    • Employing specific formulas or methods to find values from contextual clues (e.g., height of a tower from angle of elevation).
