Maths Chapter 11 Trigonometric Functions and Their Graphs 1st Year MCQs

On this page, you will get Maths Chapter 11 Trigonometric Functions and Their Graphs 1st Year MCQs with Answers. The trigonometric portion is very important for Entry tests. In the entry test, most of the questions are asked from the Trigonometric portion. So, if you have passed Intermediate, and now you are going to apply for any University, then you have to pass the entry test for the admission. Every University allows students to get admission after passing the entry test. The 1st Year 11th Chapter is about the functions of trigonometry. There is a total of six functions given in the book including sinx, cosx, tanx, cotx, cosecx, and secx. Their domain and range are very important. So, you can find the periods, amplitude, phase shift, frequency of these functions in this chapter. Further, there are different graphs of these functions that are important. So, get the important MCQs of this chapter given below.
