%md We will show you the inverse trigonometric functions. * $\sin(x)$: Its inverse is denoted by $\sin^{-1}(x)$ or $\arcsin(x)$.

We will show you the inverse trigonometric functions.

  • sin(x)\sin(x): Its inverse is denoted by sin1(x)\sin^{-1}(x) or arcsin(x)\arcsin(x).

Interact: please open in CoCalc
  • cos(x)\cos(x): Its inverse is denoted by cos1(x)\cos^{-1}(x) or arccos(x)\arccos(x).

Interact: please open in CoCalc
  • tan(x)\tan(x): Its inverse is denoted by tan1(x)\tan^{-1}(x) or arctan(x)\arctan(x). This one probably is the most important one amoung the other inverse trig functions.
