inverse trig functions table

An inverse trigonometric function table is a useful tool for understanding the relationships between angles and their trigonometric values. Below is a simplified table that shows common angles and their corresponding inverse trigonometric functions. Note that all the angles are in degrees.

Remember, the table above uses approximate values for simplification. The actual values can be more precise, depending on the level of accuracy you need.

Here's how to interpret the table:

• ${\sin }^{-1}(�)$ tells you the angle whose sine is $�$.

• ${\cos }^{-1}(�)$ tells you the angle whose cosine is $�$.

• ${\tan }^{-1}(�)$ tells you the angle whose tangent is $�$.

For instance, ${\sin }^{-1}(0.5)=30^{\circ }$, meaning that the angle whose sine is 0.5 is $30^{\circ }$.

Tables like these are useful for both Class 12 Maths and competitive exams like JEE. They help you quickly find the angle corresponding to a given trigonometric value, which is especially handy when you're solving problems related to inverse trigonometric functions. Whether it's for your Class 12 exams or preparing for JEE questions, having a good understanding of this table can be very beneficial.

inverse trigonometric functions class 12 formula

The formulas for inverse trigonometric functions in Class 12 Maths are crucial for understanding the subject and for problem-solving, especially in exams like the JEE. Here are some of the basic formulas you should know:

Inverse Sine Function (${\sin }^{-1}�$)

• Domain: $[-1,1]$
• Range: $[-\frac{�}{2},\frac{�}{2}]$

Inverse Cosine Function (${\cos }^{-1}�$)

Mastering them is also vital for tackling questions on inverse trigonometric functions in competitive exams, such as the JEE Mains and JEE Advanced. Understanding the domain and range for each function helps you grasp how and where these functions can be applied. It's crucial to familiarize yourself with these formulas as they often serve as the starting point for solving complex problems in Class 12 Maths.

Understanding the Concept of Inverse Trigonometric Functions

Inverse trigonometric functions are mathematical functions that reverse the effect of the original trigonometric functions like sine, cosine, and tangent. In Class 12 Maths, understanding this concept is crucial for mastering the subject and performing well in exams, including the JEE. If you know the sine of an angle and want to find the angle itself, you would use the inverse sine function, denoted as ${\sin }^{-1}(�)$. The idea is to understand what angle produced a particular trigonometric value. These functions have specific domains and ranges, which is a key part of the Class 12 curriculum.

Properties and Identities of Inverse Trigonometric Functions

Properties and identities are important for solving problems involving inverse trigonometric functions. The properties usually involve relations between different inverse trigonometric functions and how they operate under addition or multiplication. You might find formulas like ${\sin }^{-1}(�)+{\cos }^{-1}(�)=\frac{�}{2}$ useful. Understanding these properties helps when you are tackling Class 12 Maths questions or JEE mains questions based on inverse trigonometric functions.

Solving Equations Using Inverse Trigonometric Functions

Equations that involve inverse trigonometric functions often appear in Class 12 Maths as well as in exams like the JEE. Solving these equations requires a good understanding of the properties and identities mentioned earlier. Techniques can include isolating the inverse trigonometric term or employing trigonometric identities to simplify the equation.

Graphs of Inverse Trigonometric Functions

Graphs play a critical role in understanding the behavior of inverse trigonometric functions. The graphs can show you the domain and range visually, making it easier to grasp. For example, the graph of ${\sin }^{-1}(�)$ can show you that it only exists between -1 and 1. Learning to plot and interpret these graphs is crucial for your Class 12 exams and JEE preparations.

Evaluating Inverse Trigonometric Functions

Being able to evaluate inverse trigonometric functions is an essential skill. This involves both manual calculations and using calculators proficiently. You might need to find the angle whose cosine is 0.5 or evaluate ${\tan }^{-1}(1)$, for example. These skills are indispensable in both Class 12 Maths and competitive exams like the JEE.

Applications of Inverse Trigonometric Functions in Real-Life Scenarios

Inverse trigonometric functions are not just theoretical; they have numerous real-life applications. They are used in fields like engineering, physics, and computer science for solving practical problems. Whether it's calculating angles in construction or interpreting data in scientific research, these functions play a crucial role.
