Sin 60 X Cos 30 Cos 60 X Sin 30

Sin 60 X Cos 30 Cos 60 X Sin 30. We need to evaluate cos cos 60 ∘ × cos 30 ∘ + sin 60 ∘ × sin30 ∘ Solution We know that cos 60= 1/2 cos 30= √3/2 sin 60= √3/2 sin 30=1/2 Substituting all the values in the given equation we get ⇒ [latex]\frac{1}{2}\times \frac{\sqrt{3}}{2} + \frac{\sqrt{3}}{2} \times \frac{1}{2}[/latex] ⇒ [latex]\frac{\sqrt{3}}{4} + \frac{\sqrt{3}}{4}[/latex].

sin(30o) = 1 2 cos(30o) = √3 2 sin(60o) = √3 2 cos(60o) = 1 2 So sin(60o) ⋅ cos(30o) +sin(30o) ⋅ cos(60o) = ( √3 2)( √3 2) + (1 2)(1 2) = 3 4 + 1 4 = 1 Answer link.

Evaluate Cos 60° × Cos 30° + Sin 60° × Sin 30° [Solved]

Ex 82 1Evaluate the following (i) sin 60 cos 30 + sin 30 cos 60 We know that sin 60 = 3/2 cos 30 = 3/2 sin 30 = 1/2 cos 60 = 1/2Putting all values sin 60 cos 30 + sin 30 cos 60 = ( 3/2) ( 3/2)+(1/2) (1/2) = ( 3 3)/(2.

How do you find the exact value of sin60°cos30 Socratic

Cos x = cos60*cos 30 +sin60 *sin30 =1/2 * root3/2 + root3/2 *1/2 =root3 /4 + root3/4 =2root3 /4 =root3 /2 Cosx = cos30 x=30 degrees! Hope it helps you dear!!.
