The wavy curve method is also known as the “sign-chart” method. It is a technique used in mathematics to solve inequalities, particularly those involving trigonometric, polynomial, and rational functions. It’s a graphical representation that helps us understand the nature of the function and the intervals where it’s positive or negative. How wavy curve method works?

A periodic function is a mathematical function that repeats its values in a predictable pattern over a specific interval. This interval is known as the period of the function. In other words, if you were to graph a periodic function, you would observe the same pattern repeating at regular intervals Definition A function is said

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

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