Question

Drawe a line segment of 7 cm and divide it
into 5
equal parts​

Answer 1

Answer:

Given that

Tan(cos inverse of x ) =

sin (cos inverse of 1/2)

i.e sin ( cos inverse of 1/2) =

sin (sin inverse of pie - 1/2)

= pie by 2

Therefore

Tan (cos inverse of x) = pie by 2

Cos inverse of x =

tan inverse of pie by 2

We know that tan inverse of pie by 2 =0

Therefore cos inverse of x =0

i.e, x=pie by 2.
