Cos Root 3 Over 2
Cos Root 3 Over 2. And cos function is negative in 2nd and 3rd quadrant. 1 over 2 60° ;
And use the pythagorean theorem to solve for y. Now, were there not a 3x and it were just an x, we would just look for where cosx = √3 2. Web cos 30° = √3/2.
Web If The Sin 60° Is Square Root 3 Over 2, Then The Cos ____° = _____.
Web given, cos 30° = square root 3 over 2. Cos 30° = √3/2 is an irrational number and equals to 0.8660254037 (decimal form). Now, were there not a 3x and it were just an x, we would just look for where cosx = √3 2.
Square Root 2 Over 2 30° ;
Take the inverse cosine of both sides of the equation to extract x x from inside the cosine. In this case, it's not much different. 1 over 2 60° ;
− √3 2 = Cos(Π− Π 6) Or Cos(Π+ Π 6) As Arccosx Range Is In [0,Π]Cos(Π + Π.
Web answered • expert verified. As − √3 2 isn egative. Square root 3 over 2 60° ;
We Have To Find The Value Of Sin 60° We Know, The Sine And Cosine Functions Are Complementary Functions.
(√3) 2 + y 2 = 2 2. And cos function is negative in 2nd and 3rd quadrant. Web cos 30° = √3/2.
Web Cos (X) = √3 2 Cos ( X) = 3 2.
3 + y 2 = 4. Therefore, the exact value of cos 30 degrees is written as 0.8660 approx. And use the pythagorean theorem to solve for y.
