Trigonometry

Trigonometry is an important chapter in GCSE mathematics. The GCSE lays out the syllabus in increasing difficulty levels. Students who familiarize themselves with the foundation tier can appear for the higher tier. The course of study equips students for advanced studies. The marks are accepted at numerous reputed colleges and universities.

What do you need to study in trigonometry?

GCSE trigonometry covers the following chapters:

1. Bearings

• Measuring bearings
• Determining angles of the bearings

2. Pythagoras theorem

• Understanding Pythagoras theorem and its basics
• Determining one side of the triangle if two sides are given

3. Triangle intercept theorem

• Understand the theorem
• Derive values in triangle problems using the theorem

4. Sine and cosine formulae

• Understand the formulae and their values
• Find the area of a triangle using sine and cosine rules

5. Sin, cos and tan graphs

• Understand the sin, cos and tan graphs.
• Plot sin, cos and tan graphs for given values
• Derive sides of triangles using the sin, cos and tan values

6. Similar triangles

• Understand the concept of similar triangles
• Understand the conditions that make two or more triangles similar
• Solve triangle problems using principles of similar triangles.

What is the difficulty level of trigonometry in GCSE mathematics?

GCSE lays out the syllabus in a progressive fashion. Problems in the foundation tier are easier and deal with basic concepts. As the student advances to the higher tier, its difficulty level also increases. Trigonometry carries around 15% weightage in foundation tier and 20% weightage in the higher tier. So, students should prepare accordingly. Only when they have attained confidence to clear the higher tier, they should appear for it.

What skills do you learn in GCSE mathematics trigonometry?

Trigonometry equips students with the following skills:

• Problem-solving skills: Understanding the basics of trigonometric formulae and using them to solve different problems
• Application in real life: Using formulae, theorems, and values in solving everyday skills
• Confidence of problem-solving: Students develop confidence in solving easy as well as tough questions based on trigonometry. They are well-equipped to go for advanced studies.

Is it tough to clear trigonometry in GCSE mathematics exams?

Trigonometry is one of the easiest yet trickiest sections in GCSE mathematics. You have to pay attention to the basic formulae, their derivation, and usage in the questions. You should first prepare for the foundation tier. It has easier questions and lets you know your understanding of the chapter. After clearing it, you should go for a higher tier. However, in both tiers, the following points should be followed:

• Solve mock test papers: Several online resources, as well as offline resources, offer mock tests. You should solve it as much as possible. It will help you in confidence-building. It will also let you know your preparations and help in time management.
• Do not rush: If you have cleared the foundation tier, do not rush to appear in the higher tier. Your attention should be on completing and understanding the whole syllabus first. Prepare rigorously before appearing for a higher tier. Otherwise, your unpreparedness can lead to disqualification. It is reasonable to take time, prepare well and clear the exam.
