Inverse Trigonometric Functions Properties
Inverse geometrical functions are characterised as the backward elements of the fundamental mathematical functions—sine, cosine, tangent, cotangent, secant, and cosecant functions. They are also called arcus functions, anti-trigonometric functions, or cyclometric functions.
These inverse functions in geometry are used to get the point with any of the geometry proportions. The opposite geometry functions have significant applications in designing, material science, calculation, and route.
Inverse Trigonometric FunctionsInverse mathematical functions are likewise called “Arc Functions” since they produce the length of bend expected to acquire that specific worth for a given estimation of geometrical functions. The converse geometrical functions play out the contrary activity of the mathematical functions, for example, sine, cosine, digression, cosecant, secant, and cotangent. We realise that mathematical functions are particularly material to the correct point triangle. These six significant functions are used to discover the point measure in the correct triangle when different sides of the triangle measures are known.

Trigonometry Basics
Inverse fundamentals incorporate the essential geometry and geometrical proportions, for example, sin x, cos x, tan x, cosec x, sec x, and bed x.

Inverse Trigonometric Functions comes under the unit “Relations and Functions” in Class 12, which carries 10 marks in exams.
Frequently Asked Questions (FAQs)
Q: How would you settle backward trig functions?
A: To locate the reverse of an equation, for example, sin x = 1/2, settle for the accompanying assertion: “x is equivalent to the point whose sine is 1/2.” In the trig talk, you compose this assertion as x = sin–1(1/2).Q: What are the six functions of inverse trig?
A: They are precisely the inverses of the functions of sine, cosine, tangent, cotangent, secant, and cosecant. They are used to derive an angle from each of the trigonometric ratios of the angles.Q: Is SEC the inverse of cos?
A: The secant is the equivalent of cosine. It is the proportion of the hypotenuse to the side neighbouring a given point in a right triangle.Q: What is the converse of Cot 1?
A: The backward of the cotangent function is called inverse cotangent or arccot. It is meant by cot-1x. The area and scope of arccot work is - ∞Q: What is the inverse of cosine called?
A: The inverse of cosine is called arccosine. Dates Section:| Domain | national |
