Sin Inverse X Cos Inverse X Is Equal To 5 Then X Is Equal To
The graphs of the functions y.
Sin inverse x cos inverse x is equal to 5 then x is equal to. The angles are usually the numerically smallest angles except in the case of cot 1 x and. When the cosine of y is equal to x. Trigonometry is a part of geometry where we learn about the relationships between angles and sides of a right angled triangle in class 11 and 12 maths syllabus you will come across a list of trigonometry formulas based on the functions and ratios such as sin cos and tan similarly we have learned about inverse trigonometry concepts also. Cos y x.
If cos sin 1 2 5 cos 1 x 0 then x is equal to a 1 5 b 2 5 c 0 d 1. A unique platform where students can interact with teachers experts students to get solutions to their queries. Sin 1x cos 1x tan 1x etc. These are also written as arc sinx arc cosx etc.
The graphs of the functions y cos x and y cos 1 x are reflections of each other about the line y x. Then the arccosine of x is equal to the inverse cosine function of x which is equal to y. The arccosine of x is defined as the inverse cosine function of x when 1 x 1. Arccos x cos 1 x y here cos 1 x means the inverse cosine and does not mean cosine to the power of 1.
Welcome to sarthaks econnect. Denote angles or real numbers whose sine is x whose cosine is x and whose tangent is x provided that the answers given are numerically smallest available. The inverse trigonometric functions denoted by sin 1x or arc sinx cos x etc denote the angles whose sine cosine etc is equal to x. The inverse sine function see figure 5 is defined as the inverse of the restricted sine function y sin x figure 5 graph of inverse sine function.
