Answer:

mark me as the brainliest and see the answer in the step by step explaination section.

Step-by-step explanation:

Given cos

−1

(

b

y

)=log(

n

x

)

n

(

b

y

)=cos{nlog(

n

x

)}

y=bcos{nlog(

n

x

)}

Differentiate with respect to x we get

⇒y

1

=−bsin{nlog(

n

x

)}×

x

n

⇒xy

1

=−bnsin{nlog(

n

x

)}

Again differentiate with respect to x we get

⇒xy

2

+y

1

=−bncos{nlog(

n

x

)}×

x

n

⇒x

2

y

2

+xy

1

=−bn

2

cos{nlog(

n

x

)}

Since y=bcos{nlog(

n

x

)}, we get

x

2

y

2

+xy

1

=−n

2

y
