Question

cos54°cosec54°tan54° gibe me solution step by step

Answer 1

Hi ,

We know that,
_____________________
1 ) cosA / sinA = cot A

2 ) cot A tanA = 1

______________________

Here A = 54°

Cos 54° Cosec 54° tan 54°

= Cos 54° × 1/ sin 54° × tan 54°

= ( Cos54° / sin 54° ) × tan 54°

= Cot 54° × tan 54°

= 1

I hope this helps you.

:)

Answer 2

Cos54*cosec54*tan54*
Cos(90-36)*cosec(90-36)*tan(90-36)
Sin36*sec36*cot36
Sin36*(1/cos36)*(cos36/sin36)
=1
