Inverse of Cosine Function | ( \cos^{-1}x ) | Inverse Trigonometric Function | CBSE Class 12 Maths

Inverse of Cosine Function | ( \cos^{-1}x ) | Inverse Trigonometric Function | CBSE Class 12 Maths The inverse cosine function, written as ( \cos^{-1}x ) or arccos(x), is an important concept in Inverse Trigonometric Functions for CBSE Class 12 Maths and JEE Main. It helps us find the angle whose cosine value is given. The cosine function is not one–one on all real numbers, so its domain is restricted to the interval [0, π] in order to define its inverse. When this restriction is applied, the inverse cosine function becomes well defined. Definition: If ( \cos \theta = x ) and ( \theta \in [0, \pi] ), then ( \theta = \cos^{-1}x ) Domain: ([-1,1]) Range: ([0,\pi]) Important Values: ( \cos^{-1}(1) = 0 ) ( \cos^{-1}(0) = \frac{\pi}{2} ) ( \cos^{-1}(-1) = \pi ) Inverse cosine functions are widely used in trigonometric equations, calculus, limits, and integrals. This concept is very important for CBSE Board Exams, JEE Main preparation, and competitive exams. #maths #Class12Maths #CBSEMaths #InverseTrigonometricFunctions #CosInverse #Arccos #Trigonometry #JEEMaths #MathConcept #MathTeacher #Calculus #BoardExamPreparation #MathTricks #MathShorts #StudyMaths #MathEducation #LearnMaths #RNJha #CreativeLearning #MathsClass12 #JEEPreparation #TrigonometryConcept #MathsLecture #Education #MathsVideo
