**INTRODUCTION:**

Tuition Farm’s live online grinds classes are taught by **highly qualified and experienced teachers**, who are experts in their subject.

Classes are presented in a **lecture style format** with a **Q & A session** at the end.

Our style of teaching provides students with the **opportunity** to learn in an **uninterrupted environment** and equips them with the **fundamental skills** required for life in higher education.

We pride ourselves on providing **high quality learning resources** that will help students **achieve higher exam results**.

**OUR GRINDS COURSE:**

This course runs to** April 2022** and covers all the content from the current curriculum.

**All classes are recorded**, which means students can catch up on any classes they may have missed or use later for revision.

All student gets a **complete set of class revision notes** in advance of each lesson.

The total cost of this online grinds course is **only** **€239**.

Functions and their graphical representations will be discussed. Questions will be completed using different factorization methods such as the difference between two squares, and the manipulation of algebraic formulae, for instance algebraic fractions. Logarithms and Exponential functions will also be examined.

A recap on the rules for logarithmic and exponential functions will be discussed. This will be followed by several examples on how to manipulate logarithmic functions and solve such formulae. Methods such as ‘u substitution’ will also be considered.
Manipulation and simplification of surds will be covered after which several cases of simultaneous equations will be completed. Examples of how to determine the roots of a cubic equation will also be explained.

Examples of solving algebraic inequalities will be discussed and how to graphically represent these solutions. Following this, discriminants will be reviewed and how to analyse the value obtained from them. Finally, the absolute modulus will be discussed and how to solve equations with absolute modulus. Exam questions will be answered and explained.

The difference between a sequence and a series is explained. A method of determining if a series is arithmetic or geometric is carried out as well as an investigation into both. Limits are introduced and how to solve such problems. Finally, infinite series and sequences are introduced and their applications such as reoccurring decimals.

Percentage profit and loss is discussed. Different types of income tax are also explained, such as PRSI and USC. An example of present and future value analyzed. Compound interest examples are then carried out. Depreciation examples are completed as well as different interest period and rates questions. Finally, savings, investments, loans and mortgages questions are carried out using both the amortization formula and sequences and series.

An explanation of why complex number is needed. The Argand Diagram is introduced and how to analyze the modulus and the argument from the diagram as well as from their equations. Operations on complex numbers are carried out, such as their sum, products, addition and multiplication. Complex equations are also introduced and how to analyze their solutions.

Focusing on Complex Equations and the Conjugate Root Theorem. An explanation of the polar form is given and a step by step analysis is provided on transforming from the cartesian to polar coordinates. Operations on the polar form of the complex number will be carried out. Finally, De Moivre’s Theorem will be introduced as well as several examples of its uses.

We review Pythagorus’ Theorem and different equations such as the arc of a circle to solve several problems. The unit circle and its properties will be presented. Several examples on solving trigonometric functions are carried out. A step-by-step guide to drawing trigonometric lines is introduced and their properties such as range, period etc.

Different geometric formulas using trigonometry are given and several examples of using such formulae are carried out. Several examples are calculated to demonstrate where trigonometry can be used to solve 2D and 3D problems. Derivations for trigonometric formula are given that are required for the exam and several exam questions will be completed.

Different formulae for properties of a line are analyzed, slope, perpendicular distance, midpoint etc. Problems including areas of triangles, dividing lines in ratios and perpendicular distance are solved demonstrating uses of these formulae. The circle formula is also introduced and how to determine the radius and centre from the equation of a circle.

The circle is introduced and how to write the equation of a circle given certain information. Several examples are then carried out involving a line and a circle, touching circles, using algebraic and geometric approaches.

An introduction to Permutations and Combinatorics. Several example questions are conducted to demonstrate applications of the above. Probability definitions are introduced and discussed, following a review on how permutations and combinatorics can be applied to probability questions. Probability formulae are introduced and are used to solve problems related to probability theory.

The concept of a probability distribution and expected values is examined. Examples of where one can use the expected value is also considered. The Bernoulli Trials is introduced, and several problems are solved using this method. Questions on the margin of error, confidence levels, p values and hypothesis testing are discussed. These concepts will be introduced in statistics.

Different types of data and sampling are explained, and statistical definitions are also given. Methods of recognizing bias and limits are explained, such as mean, median mode, skewed data etc. The standard deviation is introduced and how to calculate its value from a data set. Finally, percentiles, histograms, stem and leaf plots, bar charts and scatter plots are discussed where the correlation fit, line of best fit and clusters are explained for the latter.

The concept of a probability distribution is explained. Bernoulli trials and their uses are also introduced, and several examples are carried out. The empirical rule is stated and definitions such as the margin of error, confidence intervals and constructing these are explained. Finally, hypothesis tests are completed using both p values and confidence intervals.

The structure of an answer using proof by induction is introduced. A step-by-step guide to solutions of the three different types of induction questions (Summation, division and inequality) is provided and example questions will be answered. Common questions and De Moivres proof are also provided.
