Question

the value of sin(2pi+pi/6) +cos(2pi+pi/3) is equal to​

Answer 1

Answer:

sin (2pi+pi/6) + cos(2pi+pi/3) = sin ( pi/6) + cos ( pi/3 )

= sin (30°) + cos ( 60°)

= 1/2 + 1/2

=1

Explanation:

Using the reduction formula of trigonometry

sin(2pi + theta) = sin(theta)

cos(2pi+ theta) = cos (theta)
