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 […]

We often need to convert inverse of tan to either inverse of cos, sin, sec, cosec , cot .In this post we will see how we can do it easily Inverse of tan to inverse of sin Case 1$tan^{-1} x$ and x > 0 Now we can write as $\theta=tan^{-1} x$$tan \theta =x$ Now we

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

inverse trigonometric functions table will be a very useful to immediately find out the inverse trigonometric functions values Inverse of sin and cos table Inverse of tan and cot table Inverse of cosec and sec table

Here in this post ,we will check out how to draw the graph of sin inverse sin x i.e $f(x) = sin^{-1} sin (x)$ We know by definition $f(x) = sin^{-1} sin (x) = x $ if $x \in [-\pi/2, \pi/2]$ Lets check out the other values if $x \in (\pi/2, 3\pi/2]$ $\pi/2 < x
