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 […]

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

What is odd functions An odd function is a function f(x) that satisfies the property f(-x) = -f(x) for all x in the domain of the function. In other words, an odd function is symmetric with respect to the origin. Geometrically, an odd function has the property that if you rotate the graph of the

What is even functions Examples (1) Polynomial functions Any polynomial with only even degree terms is an even function. For example, f(x) = 6×8 – 6×2 – 5. f(-x)= 6(-x)^8 -6(-x)^2 – 5 =6x^8 -6x^2 -5= f(x) (2) Cosine Function [cos(x)] The cosine function is defined as the ratio of the adjacent side to the hypotenuse in a right-angled
