How is sine50 divided by sine 36 equals 1.303?
Try calculating the sine functions on a scientific calculator, then do the division. And make sure the calculator is set to the correct angular measurement (radians, or degrees, whatever you want to calculate).
What is a value equal to sin 312?
That depends whether 312 is in degrees or in radians. Just open your scientific calculator (there is one included on most computers; don't forget to set it to "scientific"), select the correct angular measurement (usually degrees or radians), and do the calculation.-----If you don't have a scientific calculator you can use google: just enter sin 312 radians or sin 312 degrees.For more general expressions use the link attached below. For example, you can enter sin(312)+cos(312). This site will assume degrees in this instance but offer you the option of calculating the result for radians.
If you have Cos theta equals 0.92568 How do you find theta in radians?
cos(t) = 0.92568 therefore t = cos-1(0.92568) = 0.3880. If the answer comes out as 22.23, the calculator is set to degrees. Simply multiply that result by pi/180 to convert to radians (or reset the calculator to work in radians). Excel, for example, works in radians. From that primary value you get t = 0.3880 + 2*k*pi and t = 2*k*pi - 0.3880 for all integer values of k.
What is the value of sin22?
That depends on what angular measurement is used. Set your scientific calculator to the desired angular measurement (either degrees, or radians), then press 22, followed by sin. Or in more modern calculators, you press sin, followed by 22, instead.
Do you measure angles in anything other than degrees?
You can measure angles in degrees. However, The other common measurement for angles is radians. For this measurement, consider the unit circle (a circle of radius 1) whose center is the vertex of the angle in question. Then the angle cuts off an arc of the circle, and the length of that arc is the radian measure of the angle. It is easy to convert between degree measurement and radian measurement. The circumference of the entire circle is 2 ( is about 3.14159), so it follows that 360° equals 2 radians. Hence, 1° equals /180 radians, and 1 radian equals 180/ degrees. Most calculators can be set to use angles measured with either degrees or radians. Be sure you know what mode your calculator is using.
How do you do radian functions?
Just as you can measure a distance in metres and centimetres or in feet and inches, you can measure angles in degrees or radians. You can either set your calculator to radians, or convert from radians to degrees using 1 radian = 180/pi degrees = 57.3 degrees approx or 1 degree = pi/180 radians.

What is sin pi over 6?
You can calculate that on any scientific calculator. Presumably, for any expression that involves "pi" the angle should be in radians, so be sure to set the calculator to radians first.

Is the theta in a projectile equation measured in degrees or radians?
The equations for projectiles shouldn't just have theta, they should have sin(theta) or cos(theta). As long as you have your calculator set in the right mode, either will work when you evaluate sin or cosine. Example: Say you have a projectile launched at 30 degrees above horizontal. In order to find the y velocity, you will have to calculate sin(30) with you calculator in degree mode. If instead you called this angle pi/6 (the same angle, just in radians), you could enter sin(pi/6) in your calculator in radians mode and get the same answer.
What is the angle with a tangent ratio of 0.9325?
Take up any scientific calculator - the one that comes with Windows works just fine. Write the ratio, then press the keys for "inverse", followed by "tan". Before doing that, be sure to set the calculator to the desired type of angular measurement - degrees, or radians, depending what you want.Or, in Excel, you can type: = atan(0.9325) However, this will return the angle in radians; you then have to convert that to degrees. Note: There may be angles in other quadrants with the same tangent ratio (or the same value for other trigonometric function); the calculator only shows you one solution. In the case of the tangent function, you can add pi radians, or 180 degrees, to get the other solution in the interval from 0 to 360 degrees.
If you have Cos theta equals 0.92568 How do you find theta in radians?
cos(t) = 0.92568 therefore t = cos-1(0.92568) = 0.3880. If the answer comes out as 22.23, the calculator is set to degrees. Simply multiply that result by pi/180 to convert to radians (or reset the calculator to work in radians). Excel, for example, works in radians. From that primary value you get t = 0.3880 + 2*k*pi and t = 2*k*pi - 0.3880 for all integer values of k.

How do you solve cosine 140?
Well, the usual way would be to use a scientific calculator - one that has support for trigonometric functions such as cosine. Make sure the calculator is set to "degrees", since I assume the "140" represents degrees. Of course you might also use the infinite series for the cosine function (which is basically what the calculator does). Convert the angle to radians, then use the infinite Tailor series: cos x = 1 - x2/2! + x4/4! - x6/6! + ...
How do I find Sin A .42 is A is an acute angle. And how do i enter that on a calculator?
If sin(A) = 0.42 then A = arcsin(0.42).On calculators, the arcsin key is usually reached by using another key before the sin key, and is shown as "sin to the power -1".Make sure that your calculator is set to degrees rather than radians (to check this, try sin(90). If the answer is 1 the calculator is in degree mode; if it is 0.8940 it is in radian mode.
Relationship between degree of measure of a central angle and the arc it intercepts?
Arc length is equal to radius times the angle the arc subtends (makes) at the centre of the circle, but the angle needs to be in radians. Set your calculator to radians instead of degrees, or, to change degrees to radians, divide by 180 and times pi. The formula comes from the fact that the length of the arc is proportional to the circumference of the circle in the same ratio as the angle at the centre is to the complete revolution at the centre, so length of arc: circumference of circle = angle size : 360o arc/(2*pi*r) = angle in degrees/360 or angle in radians/(2*pi) so arc length is angle in degrees divided by 360, times the circumference of the circle. Answer will be in the same measurement unit as the radius.
