How do you find cosine squared at 30 degrees?
cos(30) = sqrt(3)/2 so cosine squared is 3/4.
What is cos of angle a with a hypotenuse of 13 and adjacent of 5 and a opposite of 12?
Cos(angle) = adjacent / hypotenuse. Cos(a) = a/h Substitute Cos(X) = 5/13 = 0.384615... A = Cos^*-1( 0.384615 .... A = 67.38013505... degrees.
What is the cos of 30?
0.866
What is the absolute value of cos 65 degrees?
0.422618262
What is the cos of angle a if the opposite is 5 the adjacent is 12 and the hypotenuse is 13?
It is: cos^-1(12/13) = 22.61986495 degrees
What is the value of cos 30 degrees?
The value of cos 30 degrees is (\frac{\sqrt{3}}{2}). This is a commonly used value in trigonometry, derived from the properties of a 30-60-90 triangle. In this triangle, the ratio of the adjacent side to the hypotenuse corresponds to the cosine of 30 degrees.
What is the cosine 30 degrees?
cos(30 deg) = sqrt(3)/2 = 0.8660 approx.
How do you turn cosine of 30 degrees into a fraction?
Cos(30) = sqrt(3)/2 = 0.866025403.... ( Which is irrational).
What is the exact value answers in degrees of two cos x minus radical three equals zero?
30 degrees explanation 2Cosx-radical 3=0 Then 2cosx=radical 3 and cos x=(radical 3)/2 Now remember that cos 300 is (radical 3)/2 from the 30/60/90 triangle. So the answer is 30 degrees.
What is cos15 degrees?
The cosine of 15 degrees can be calculated using the cosine subtraction formula: (\cos(15^\circ) = \cos(45^\circ - 30^\circ)). This gives us (\cos(15^\circ) = \cos(45^\circ)\cos(30^\circ) + \sin(45^\circ)\sin(30^\circ). Substituting the known values, (\cos(45^\circ) = \frac{\sqrt{2}}{2}), (\cos(30^\circ) = \frac{\sqrt{3}}{2}), (\sin(45^\circ) = \frac{\sqrt{2}}{2}), and (\sin(30^\circ) = \frac{1}{2}), we find that (\cos(15^\circ) = \frac{\sqrt{6} + \sqrt{2}}{4}).
What is cos 510 degrees.. Not it decimal form but by using a fraction including any radicals if necessary?
510 ~ (510-360) ~ 150 Cos 510 = Cos 150 = - Cos 30 = - ( radical 3 ) / 2
What is cos 30?
cos(30 = 0.8660254038
How do you find cosine squared at 30 degrees?
cos(30) = sqrt(3)/2 so cosine squared is 3/4.
What is the value of cos 40 degrees?
The value of cos 40 degrees is approximately 0.766.
What is Cos 15?
The cosine of 15 degrees can be calculated using the cosine subtraction formula: ( \cos(15^\circ) = \cos(45^\circ - 30^\circ) ). This gives us ( \cos(15^\circ) = \cos 45^\circ \cos 30^\circ + \sin 45^\circ \sin 30^\circ ). Plugging in the known values, ( \cos 45^\circ = \frac{\sqrt{2}}{2} ), ( \cos 30^\circ = \frac{\sqrt{3}}{2} ), ( \sin 45^\circ = \frac{\sqrt{2}}{2} ), and ( \sin 30^\circ = \frac{1}{2} ), we find that ( \cos 15^\circ = \frac{\sqrt{6} + \sqrt{2}}{4} ).
