Question

Q3. If sin 0 = cos 0, find the value of 0
​

Answer 1

Given,

sin0 = cos0

To find,

Find the value of 0

Solution,

Acording to the question,

sin O = cos O

By rearranging, we get

sin O / cos O = 1

⇒ tan O = 1

We know that,

tan 45° = 1

So,

tan O = tan 45°

⇒ O = 45⁰

Hence, the value of 0 in the given equation is 45⁰.
