Inverse trig functions in matlab2/6/2024 We will understand the domain and range of these functions in the following sections. Here, we have chosen random values for x in the domain of respective inverse trigonometric functions. We can plot the graphs of different inverse trigonometric functions with their range of principal values. Let us study the properties of inverse trigonometric functions using their graph, domain, and range in the following sections. These formulas resemble and are derived from the triple angle formulas of trigonometry. The triple of the inverse trigonometric functions can be solved to form a single inverse trigonometric function as per the below set of formulas. Triple of Inverse Trigonometric Function Formulas These formulas are derived from the double angle formulas of trigonometry. The double of an inverse trigonometric function can be solved to form a single trigonometric function as per the below set of formulas. The inverse trigonometric formula of inverse sine, inverse cosine, and inverse tangent can also be expressed in the following forms.ĭouble of Inverse Trigonometric Function Formulas This follows from the trigonometric functions where sin and cosecant are reciprocal to each other, tangent and cotangent are reciprocal to each other, and cos and secant are reciprocal to each other. The inverse trigonometric function for reciprocal values of x converts the given inverse trigonometric function into its reciprocal function. Inverse Trigonometric Function Formulas for Reciprocal Functions And for functions of cosine, secant, cotangent, the negatives of the domain are translated as the subtraction of the function from the π value. For the inverse trigonometric functions of sine, tangent, cosecant, the negative of the values are translated as the negatives of the function. The inverse trigonometric function formula for arbitrary values is applicable for all the six trigonometric functions. Inverse Trigonometric Function Formulas for Arbitrary Values Further all the basic trigonometric function formulas have been transformed to the inverse trigonometric function formulas and are classified here as the following four sets of formulas. These formulas are helpful to convert one function to another, to find the principal angle values of the functions, and to perform numerous arithmetic operations across these inverse trigonometric functions. The list of inverse trigonometric formulas has been grouped under the following formulas. This means that if y = f(x), then x = f -1(y).Īn example of inverse trigonometric function is x = sin -1y. It is used in diverse fields like geometry, engineering, physics, etc.Ĭonsider, the function y = f(x), and x = g(y) then the inverse function can be written as g = f -1, The inverse trigonometric functions are used to find the angle of a triangle from any of the trigonometric functions. The inverse trigonometric functions are written using arc-prefix like arcsin(x), arccos(x), arctan(x), arccsc(x), arcsec(x), arccot(x). Inverse trigonometric functions are the inverse functions of the basic trigonometric functions which are sine, cosine, tangent, cotangent, secant, and cosecant functions. Inverse trigonometric functions are also known as the anti-trigonometric functions/ arcus functions/ cyclometric functions. All the trigonometric formulas can be transformed into inverse trigonometric function formulas. Here, x can have values in whole numbers, decimals, fractions, or exponents. The basic trigonometric function of sin θ = x, can be changed to sin -1 x = θ. Inverse trigonometric functions are the inverse functions relating to the basic trigonometric functions. Inverse Trigonometric Functions Domain and Range What are Inverse Trigonometric Functions? Here we shall try to understand the transformation of the trigonometric formulas to inverse trigonometric formulas. Inverse trigonometric functions have all the formulas of the basic trigonometric functions, which include the sum of functions, double and triple of a function. The inverse trigonometric functions on the other hand are denoted as sin -1x, cos -1x, cot -1 x, tan -1 x, cosec -1 x, and sec -1 x. The basic trigonometric functions are sin, cos, tan, cosec, sec, and cot. Similarly, we have inverse trigonometry functions. In trigonometry, we learn about the relationships between angles and sides in a right-angled triangle. The domain and the range of the trigonometric functions are converted to the range and domain of the inverse trigonometric functions. Inverse trigonometric functions, as a topic of learning, are closely related to the basic trigonometric functions.
