If sinθ - cosθ = 0, find the value of 'θ'.

Answer:

Explanation:

For solution 1,
We do very simple steps. We first add + cos on both sides and as they are equal! We can then divide the sin by cos putting 1 on the right side. Now we get sin/ cos = tan. And from the value table, we know tan 45° = 1. Therefore θ = 45°

For solution 2,
We multiply both sides by
1. (Sin + Cos)
2. We get (a-b)(a+b) on the LHS which is equal        to a^2 - b^2.
3. We know, cos^2 x = 1 - sin^2 x

After this, we use the solving steps and we can get the value of the unknown angle in the question!
