Question

please solve my question guys ​

Answer 1

A = { theta : sin theta = Tan theta}

B = { theta : cos theta = 1}

We know that,

Sin theta = Tan theta when theta = 0°

So, here, theta = 0°

In Set B, cos theta = 1,

We know that, cos theta = 1 when theta = 0 °

So, in both sets A and B, theta = 0°. This means that both are equal sets.

So, Option ( a ) is correct.

( a ). A = B.

Answer 2

The correct option is a

A = B
