Question

If 1+(1/X) = 2Cospi/4 , then what is the value of X^12 ?

Answer 1

hey mate

given here

1+(1/X) = 2Cos (π/4)

find here

x¹²=?

so

=>1+(1/X) = 2Cos (π/4)

we know that

cos π/4= 1/√2

then,

=>1+(1/x)= 2× 1/√2

=>1/x = √2 -1

=>x= 1/(√2-1)

=>x= (√2+1)/(√2+1)(√2-1)

=>x=(√2+1)/(2-1)

=>x=(√2+1)

put value √2=1.414

so,

=> x = 1.414 + 1

= 2.414

I hopes its help's u.
