Answer 2

Answer:

Sin30°= 1/2 , Values of Sin 0° ,

Sin30° , Sin45° ,Sin60° ,Sin90°

may be kept in mind by undernoted way .

Sin0° = √0/√4 =0 =Cos 90°

Sin30°=√1/√4 =1/2 =Cos60°

Sin45° =√2/√4=1/√2 =Cos45°

Sin 60°=√3/√4=√3/2 =Cos30°

Sin90° = √4/√4 = 1 = Cos0°

we can calculate Sin of any angle.

First draw a triangle whose one angle 90° , and other one angle say 35° .The length of the side opposit to the 35°angle is to be called ‘perpendicular’(P). Measure it .Other side except ‘hypotenuse’(H) is to be called ‘base’(B).Also measure it . Measure also hypotenuse (H).

Now Sin35°=P/H, Cos35°=B/H

Tan35°=P/B
