Question

Sin 30 + 2 cos 60sin 90 + cos 180 + tg 360 √2sin45 + √3tg30

Answer 1

Sin30+2cos60=1/2+1=1,5
sin90+cos180+tg360=1-1+0=0
√2sin45+√3tg30=1+1=2

Answer 2

Sin 30 = 0.5 2 cos 60 = 2 * 0.5 = 1 sin 90 = 1 cos 180 = -1 tg 360 = tg 0 = 0 √2 sin 45 = √2 * 0.5 = √2 / 2 √3 tg 30 = √3 * 1/√3 = 1

So, the detailed answers are: Sin 30 = 0.5 2 cos 60 = 1 sin 90 = 1 cos 180 = -1 tg 360 = 0 √2 sin 45 = √2 / 2 √3 tg 30 = 1
