Trigonometry has great weightage in entrance exams like IIT-JEE, etc. Inverse Trigonometry, Trigonometric functions, and trigonometric ratios are some of the most important topics class 11th students must focus on during preparations. Trigonometry has a minimum weightage of 8 marks in the total score of IIT-JEE. The previous year’s papers of IIT-JEE have at least 2-3 questions on this topic. Download the solution for this chapter from Vedantu and understand the concepts. Use the weight distribution in terms of marks of these questions accordingly.
3. Is trigonometry a tough topic to prepare?
Trigonometry within itself is an easy topic. The range of questions that can be framed makes it a lot harder, but, with the right preparation, it is doable. Most of the time students have this misconception that trigonometry is hard. But it requires good logic application ability which is why studying trigonometry is beneficial. It tends to help with the logical abilities of a student in problem-solving and push them into thinking further and better to solve the given question based on their knowledge. A single question in trigonometry can have multiple solutions because of the large number of formulae the topic contains. It is up to the students which methodology they choose to come up with an easier, shorter, or less time-consuming solution.
4. What is the significance of trigonometry in daily life?
Trigonometry has many uses in day-to-day life as any geometric shape can be broken down into a collection of triangles. In Mathematics, Trigonometry can be used to solve almost every kind of problem. Some of the real-life uses of trigonometry are constructions, measurement of the height of tall structures, marine biology, navigation, criminology, aviation, etc. In short, trigonometry is one of the topics which are highly applicable in real life.
5. What is the significance of the compound angles formulae in trigonometry?
As mentioned earlier, formulae in trigonometry are widely applicable within the topic itself. Every formula can be used to solve a problem if the student can take the solution forward with a logical approach. Similarly, we can solve various types of problems using the compound angles formulae as well. Students need to keep in mind the trigonometric ratios are while using the compound angles formulae and use the formula according to the given question.
