Question

How to calculate Tan inverse value

Answer 1

Answer:

We can calculate easily

Step-by-step explanation:

As we have given in the question we need to calculate the value of $tan^{-1}$, It is very easy though we should have a good knowledge of trigonometric identities and trigonometric values such as

If we have to calculate the value of $tan^{-1}[45]$=1

$tan^{-1}[0]=0$

We must have the good knowledge of trigonometric values or if you don't want to remember tan values you can remember the sin and cos values as, $tan=\dfrac{sin}{cos}$

So in this way, We can calculate the value of $tan^{-1}$
