Question

Value of the cot 10 degree

Answer 1

cot=1/tan

Answer 2

cot 10=1/tan 10

Answer 3

cot10=tan^-1(10)=5,67128181961771 (using a calculator)

Answer 4

\[\cot(x) = \frac{ 1 }{ \tan(x) }\]
\[\cot(10) = \frac{ 1 }{ \tan(10) }\]
\[\cot(10) = 5.6712818196326647\]
\[\cot(10) = 5.67\]

Answer 5

@celecity : You're correct

Answer 6

I think it's finding the exact value?

Answer 7

If it is the case,
\[\cos15^\circ\implies\cos5^\circ\implies\cos10^\circ\implies\sin10^\circ\implies\cot10^\circ\]
