Inverse Trigonometric Functions

If sin y = x, then y = sin–1x (We read it as sine inverse x)

Here, sin–1x is an inverse trigonometric function. Similarly, the other inverse trigonometric functions are as follows:

If cos y = x, then y = cos–1x If tan y = x, then y = tan–1x If cot y = x, then y = cot–1x If sec y = x, then y = sec–1x If cosec y = x, then y = cosec–1x The domains and ranges (principle value branches) of inverse trigonometric functions can be shown in a table asâ€¦To view the complete topic, please
