Question

what is the value of tan30°-cos60°

Answer 1

1/√3-1/2=2-√3/2√3 is the answer

Answer 2

hey there,

30o and 60oare angles of one of the standard triangles

sin(30o)=12

cos(30o)=√32

sin(60o)=√32

cos(60o)=12

So
sin(60o)⋅cos(30o)+sin(30o)⋅cos(60o)

=(√32)(√32)+(12)(12)=34+14

=1

Hope this helps!
