Chapter 7: Q. 85 (page 458)

Explain in your own words how you would use your calculator to find the value of $c o t^{- 1} 10$ .

Short Answer

Expert verified

The value of $c o t^{- 1} (10)$ can be calculated by using the equivalent function $\tan^{- 1} (\frac{1}{10})$ .

Step by step solution

01

Step 1. Given information.

The function $c o t^{- 1} 10$ .

02

Step 2. Convert cotangent function to tangent.

Let,

$c o t^{- 1} 10 = x c o t x = 10 s o, \tan x = (\frac{1}{c o t x}) = (\frac{1}{10}) x = \tan^{- 1} (\frac{1}{10})$

03

Step 3. Now, calculate the required value by using inverse tangent function in calculator.

As,

$c o t^{- 1} 10 = x = \tan^{- 1} (\frac{1}{10})$

Now, use calculator and type $\tan^{- 1} (\frac{1}{10})$ :

$\tan^{- 1} (\frac{1}{10}) 鈮� 5.71 掳$
