A Level Mathematics Syllabus Statement

Syllabus Content

Understand and use
tanθ = sinθ ÷ cosθ
sin²θ + cos²θ = 1
sec²θ = 1 + tan²θ and
cosec²θ = 1 + cot²θ

Here is an exam-style questions on this statement:

"In triangle ABC, the length of AB = 5cm, AC = 13cm and \( \cos B \hat AC = \frac18 \)." ... more

Trigonometry Trigonometry is a branch of mathematics that studies triangles and the relationships between their sides and the angles between these sides. Pupils begin by learning the names on the sides of a right-angled triangle relative to the angles. They then learn the ratios of the lengths of these sides and the connection these ratios have with the size of the angles. Having mastered right-angled triangle trigonometry pupils then progress to more advanced uses including the sine rule and cosine rules. The use of a scientific or graphing calculator is essential for this topic and correct, efficient use of the calculator is an important skill to develop. Here's a Trigonometry Wordsearch just for fun.
