Answer 1

Answer:

this is example and right answer ok

Answer 2

Step-by-step explanation:

Given:

$tan {}^{ - 1} x \: \: and \: \: {cot}^{ - 1} x$

To find:Find the derivative of tan^-1 x wrt to cot^-1 x

Solution:

Let

$\bold{p = tan {}^{ - 1} x }$

and

$\bold{q = cot {}^{ - 1} x}$

Find dp/dx and dq/dx

$\frac{dp}{dx} = \frac{1}{1 + {x}^{2} } \: ...eq1$

and

$\frac{dq}{dx} = - \frac{1}{1 + {x}^{2} } ...eq2$

Divide eq1 by eq2

$\frac{dp}{dq} = \frac{1}{1 + {x}^{2} } \times - \frac{1 + {x}^{2} }{1} \\ \\ \frac{dp}{dq} = - 1$

Final answer:

$\frac{dp}{dq} = - 1$
