Question

if tan theta is equal to 1 than sin theta into cos theta is equal to​

Answer 1

Answer:

1/2 is your answer

Step-by-step explanation:

Given = tan theta = 1

tan theta = 1 is only possible when theta = 45°

Now

sin45° x cos45° = ?

$1/\sqrt{2}$ / $1/\sqrt{2}$

$1 / \sqrt{4}$

1 / 2

Therefore, sin theta x cos theta = 1/2
