Mastering the sine and cosine rules is essential for solving triangles when you don't have a right angle. The area of a triangle can be calculated using various formulas, including Heron's formula, which is useful when you know the lengths of all three sides. This section also includes formulas for the area and circumference of circles, as well as the volume and surface area of various 3D shapes. Understanding radians and their relationship to degrees is crucial for working with trigonometric functions. The unit circle is your friend; make sure you know it well! Also, pay attention to the conditions under which certain formulas apply. For example, the sine rule can only be used when you have an angle and its opposite side. Practice applying these formulas in different contexts to build confidence and accuracy.

Topic 4: Statistics and Probability

Statistics and Probability are covered with formulas for mean, standard deviation, probability distributions (like binomial and normal), and hypothesis testing. The formulas for mean and standard deviation are fundamental for analyzing data sets. Understanding the properties of the binomial and normal distributions is essential for solving probability problems. The normal distribution, in particular, is widely used in statistical inference and hypothesis testing. This section also includes formulas for calculating probabilities, conditional probabilities, and expected values. Be sure to understand the difference between discrete and continuous random variables. The formula booklet provides a concise summary of the key concepts and formulas, but it's important to understand the underlying principles. Practice applying these formulas to real-world data sets to develop your statistical intuition. Understanding these concepts will not only help you in your IB exams but also in interpreting data and making informed decisions in everyday life.

Topic 5: Calculus

Calculus includes differentiation and integration formulas, chain rule, product rule, quotient rule, and applications of calculus such as finding areas and volumes. Differentiation formulas are essential for finding the rate of change of a function, while integration formulas are used to find the area under a curve. Mastering the chain rule, product rule, and quotient rule is crucial for differentiating complex functions. This section also covers applications of calculus, such as finding maxima and minima, points of inflection, and areas between curves. Understanding the fundamental theorem of calculus is essential for connecting differentiation and integration. The formula booklet provides a concise summary of the key formulas, but it's important to understand the underlying concepts. Practice applying these formulas to a variety of problems to develop your calculus skills. Calculus is a powerful tool for solving problems in physics, engineering, economics, and many other fields, so make sure you have a solid grasp of the fundamentals.
