Question

Evaluate cos(tan^-1 0)

Answer 1

Answer:

$cos(tan^{-1}(0))=1$

Step-by-step explanation:

Evaluate cos(tan^-1 0)

$cos(tan^{-1}(0))$

We know that tan(0)=0

tan (0 degree)=0

$tan^{-1}(0)=0$

Replace it in our problem

$cos(tan^{-1}(0))$

$cos(0)$

At 0 degree the cos value is 1

So co(0)=1

$cos(tan^{-1}(0))=1$
