Question

Prove that cot theta- tan theta =2cos² theta -1 ÷ sin theta cos theta = 1-2sin² theta÷sin theta . cos theta


​

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

Answer 2

Answer:

lastly answer is x =pie /2
