1st Year Maths Chapter 13+14 MCQs with Answers

If you are looking for 1st Year Maths Chapter 13+14 MCQs with Answers then on this page, you will get them. These are the final Chapters of 1st Year Maths. They are about Inverse Trigonometric Functions and Solutions of Trigonometric Equations. These chapters are short but very important for the Entry Tests. The Trigonometric functions have different domain and ranges. The inverse of these functions also has a specific domain, range, and properties. The trigonometric equation is that equation having at least one trigonometric ratio. So, this is the brief Introduction to these chapters. Now, the students should remember that the Maths portion is very important and you need to study very hard to get good marks. They have a good weightage of marks in the entry test. So, here we are giving you the important MCQs of these chapters. Have a look down to get them.
