We often need to convert inverse of sec to either inverse of cos, sin, tan, cosec , cot .In this post we will see how we can do it easily Inverse of sec to inverse of sin Case 1$sec^{-1} x$ and x > 1 Now we can write as $\theta=sec^{-1} x$$sec \theta =x$ Now we […]

Here in this post ,we will check out how to draw the graph of tan inverse tan x i.e $f(x) = tan^{-1} tan (x)$ As $tan (\pi +x ) = tan x$ This is a periodic function with period $\pi$ Also x cannot take values like $\frac {2n+1}{2} \pi$ as undefined We know by definition

In this post ,we will check what method or ways can be used to solve inverse trig equations how to solve inverse trig equations Method 1 1. Obtain the equation in the form given above using inverse trigonometric function identitiesi.e$sin^{-1} x =”value”$$cos^{-1} x=”value”$$tan^{-1} x=”value”$$cosec^{-1} x=”value”$$sec^{-1} x=”value”$$cot^{-1} x=”value”$ 2. Now we can easily find the value

Here in this post ,we will check out how to draw the graph of cos inverse cos x i.e $f(x) = cos^{-1} cos (x)$ We know by definition $f(x) = cos^{-1} cos (x) = x $ if $x \in [0, \pi]$ Lets check out the other values if $x \in (\pi, 2\pi]$ $\pi < x
