hi

Trigonometry

Step 1: Master your basic terminology you need to know. This will help with interpreting the question and then deciding on what you need to do to solve the problem. Here are some terms you will need to know:

Right angled triangle: any triangle that contains one angle of 90º.

Opposite side: when working with a right­-angled triangle and trigonometric ratios, the opposite side is the side opposite the angle in question.

Adjacent side: when working with a right­-angled triangle and trigonometric ratios, the side next to the angle in question, but not the hypotenuse.

Hypotenuse: the longest side of a right-angled triangle. It is the side opposite the right angle of a right-angled triangle.

Ratio: the relationship between two numbers indicating how many times the first number contains the second.

 You can look up more definitions in the X-kit Achieve Glossary.

 

Step 2: Master the trigonometric ratios: Cosine (cos), sine (sin) and tangent (tan) and attempt as many questions as possible with different scenarios. Here are the definitions of the mentioned ratios.

Cosine: is a trigonometric ratio defined as the adjacent side divided by the hypotenuse.

Sine: is a trigonometric ratio, expressed as opposite side divided by hypotenuse.

Tangent: is a trigonometric ratio, expressed as opposite side divided by adjacent side in a right-angled triangle.

Step 3: Master how to use your calculator to find trigonometric ratios.

Step 4: You need to know what special angles are. Do as many questions as possible that require you to find ratios without a calculator.

 

Step 5: Start with very easy questions and then move on to the hard ones. Once you are sure that you have mastered the concept that is required by doing the easy questions, then you can attempt the harder questions.

 

The trick with Trigonometry is to master the basic terminology and then attempt as many exercises as possible.
