## Is arctan adjacent over opposite?

For example if you know the hypotenuse and the side opposite the angle in question you could use the inverse sine ratio. If you know the side opposite and the side adjacent to the angle in question the inverse tangent ratio is used. … Inverse tangent is also called arctangent and is labeled tan**−**1 or arctan.

## Why is tan-1 not tan?

4 Answers. The reason that it isn’t true is that regrettably **the notation is not consistent**. For this reason many people avoid using tan−1 and use arctan instead and so on for the other trigonometric functions. That said tan−1 is logical notation and such notation as tan2 is illogical.

## Is arcsin and sin 1 the same?

**Sin-1 is the inverse of sine function**. … Arcsin α means the arc whose sine is α. Whereas 1/sin x shows the reciprocal of sine function which is also equal to cosecant function.

## Why is arcsin called arcsin?

If you have a numerical value and you want the size of the angle whose sine has this value you get something like this where the value is a number and the arcsin is expressed in degrees of arc. It essentially reverses the process of the sine function. It is called “arcsin” **because it gives you a measure of the arc.**
