Question

(Sin180+cos90) what is the value of the given expression

Answer 1

Answer:

0

Step-by-step explanation:

(Sin180+cos90)

=sin(2×90+0)+ cos(1×90+0)

=sin0 + sin0

=0+0

=0

Answer 2

As ,

• Sin 0 = 0 , Sin 90 = 1 , Sin 180 = 0

And

• Cos 0 = 1 , Cos 90 = 0 , Cos 180 = 1

So ,

• Sin 180 + Cos 90
• = 0 + 0
• = 0
