What is the cosine of a 30 degree angle?
As a decimal: 0.866 As a fraction: √(3)/2
How do you find an angle using sine cosine tangent?
If you know the angle's sine, cosine, or tangent, enter it into the calculator and press <inverse> sine, cosine, or tangent. On MS Calc, in Scientific Mode, using Degrees, enter 0.5, then check Inv and the press sin. You should get 30 degrees. The other functions work similarly.
What fraction of a pie graph is 30 degrees?
Since a complete circle is 360 degrees, a 30-degree part of a circle is 30/360, or 1/12, of the pie.
Is the cosine function an odd function?
No. Cosine, along with sec, is an even function. The odd functions are sin, tan, csc, and cot. The reason for this is because is you take the opposite of the y-value for the cosine function, the overall value of the function is not affected.Take, for example, cos(60 degrees), which equals POSITIVE 1/2.If you flip it over the x-axis, making the y's negative, it becomes cos(-60 degrees), or cos(300 degrees). This equals POSITIVE 1/2.Now let's look at an odd function. For example, sin(30 degrees) equals POSITIVE 1/2. Now take the opposite of this.sin(-30 degrees), or sin(330 degrees), equals NEGATIVE 1/2. This is because it is found in the fourth quadrant, where the y's are negative. Sine of theta, by definition, is y divided by r. If y is negative, sine is negative.
What is the value of sin 30 degrees?
Sin30 degrees is 0.50000
How do you find cosine squared at 30 degrees?
cos(30) = sqrt(3)/2 so cosine squared is 3/4.
What is cosine 30 degrees?
0.866 ( or (sqrt 3)/2 )
What is the cosine of a 30 degree angle?
As a decimal: 0.866 As a fraction: √(3)/2
What is the cosine 30 degrees?
cos(30 deg) = sqrt(3)/2 = 0.8660 approx.
How many degrees are there in a twelfth turn?
30 degrees
How many degrees in a twelfth of a turn?
30 degrees
How do you turn 30 to a fraction?
30 = 30/1 = 60/2 and so on.
What fraction of a turn is 144 degrees?
A full turn is 360 degrees Therefore 144 degrees = 144/360 turn = 12/30 = 6/15 = 2/5 turn
How do you find an angle using sine cosine tangent?
If you know the angle's sine, cosine, or tangent, enter it into the calculator and press <inverse> sine, cosine, or tangent. On MS Calc, in Scientific Mode, using Degrees, enter 0.5, then check Inv and the press sin. You should get 30 degrees. The other functions work similarly.
What the only formula you can find the exact value of cosine 30?
Cosine(30) = sqrt(3)/2
What fraction of a full rotation is 30 degrees?
1/12
What fraction is 30 degrees?
Well, isn't that a happy little question! 30 degrees is 1/12 of a full circle, which is 360 degrees. So, in fraction form, we can say that 30 degrees is 1/12 of a full rotation. Just like painting, math can be a beautiful way to express the world around us.
