Question

If tan o = √3, find the value of
sin o • cos o​

Answer 1

Given tanθ=

3

and θ is acute

Now θ lies in first quadrant, so value of θ will be 60

o

.

Now value of 1+cosθ=1+cos60=1+

3

/2

Answer 2

Answer:

tan o = √3

tan o = tan 60

o=60

sin o. cos. o

= sin 60 . cos 60

= √3/2 . 1/2

= √3/4
