Q) Evaluate: 2√2 cos 45° sin 30° + 2√3 cos 30°
Ans: Here, let’s start values of sin & cosine for θ = 300 and 450
We know that sin 300 = , cos 300 = , cos 450 =
We submit these values in the given question, we get:
2√2 cos 45° sin 30° + 2√3 cos 30°
= 2√2 + 2√3
=
= 1 + 3 = 4
Therefore, the value of 2√2 cos 45° sin 30° + 2√3 cos 30° = 4.
