Question

PROVE THAT tanA×cotA=1

Answer 1

Hope this answer helps you :)

Answer 2

Hi,
Here is the answer to your query:-

As we know that

tanA = 1/cotA

By cross multiplying we get,

tanA × cotA = 1

Hence proved.

OR

Taking L.H.S
TanA × CotA
=SinA/CosA × CosA/SinA
=1×1
=1 = R.H.S
Hence proved.
