Question 7 The distance between the points (cos30°, sin30°) and (cos60°, – sin 60°) is (A) 0 unit (B) √3 units (C) 1 unit (D) √2 unitsOur points are (cos30°, sin30°) = (√𝟑/𝟐,𝟏/𝟐) (cos60°, – sin 60°) = (𝟏/𝟐,(−√𝟑)/𝟐 ) Distance between (√𝟑/𝟐,𝟏/𝟐) and (𝟏/𝟐,(−√𝟑)/𝟐 ) is Distance = √((1/2−√3/2)^2+((−√3)/2−1/2)^2 ) = √(((1−√3)/2)^2+((−√3 − 1)/2)^2 ) = √(8/4) = √𝟐 units So, correct answer is (d)
