Question

find the differential cofficient of tanx with respect to cotx .​

Answer 1

Step-by-step explanation:

By trigonometric identities:

cot

A

=

cos

A

sin

A

=

1

tan

A

Therefore,

y

=

tan

x

(

1

tan

x

)

=

tan

x

tan

x

=

1

So,

d

y

d

x

=

0

You could try and use product rule as well as the quotient rule for

1

tan

x

and this should give you the same result of

0

.

Hope this helps!
