Question

if tan theta =1 then what is the value of sin theta.cos theta​

Answer 1

Given:

tan∅=1

→tan∅=tan45

→∅=45

To find the value of sin∅cos∅

Then,

sin∅cos∅ would be sin45cos45

Now,

Sin45cos45

=1/√2 × 1/√2

=1/2

Answer 2

Answer: 1/2

Hope this helps:

tanѲ = 1

So, Ѳ = 45°

sin45.cos45 = 1/root 2 × 1/root 2 = 1/2
