Why do I get different answers in calculator?
Each calculator may have a different algorithm for calculating the answer. Each calculator may be programed to calculate a different degree of accuracy. Each calculator may have a different number of digits it can display.
What value of sin is 1?
0.8414709848
The value of sin 1 is 0.8414709848, in radian. In trigonometry, the complete trigonometric functions and formulas are based on three primary ratios, i.e., sine, cosine, and tangent in trigonometry.
What is the exact value of sin 1?
The value of sin 1 is 0.8414709848, in radian.
Should my calculator be in radian or degree?
Quite simple. When ever the calculations you are performing, require unit of an angle as degree use degree mode and when radian is required use radian mode. For example if you are calculating a value whose formula includes a π use radian otherwise use degree.
What is the difference between sin and sin 1?
The basic difference between Sin 1degree and Sin 1 is the angle. In Sin 1, the angle is 1 radian where as in Sin 1 degree, the angle is in degrees. 1 radian = 57 degrees 16 minutes approximately. So now these two expressions become Sin 1 degree and Sin 57 degrees 16 minutes.
How do you find Sin 30 on a calculator?
To do so, put your calculator in degree mode rather than radians or other angle measurements. Then enter 30 sin (x) to see if you get the correct response, .5 If not, perhaps your calculator requires you to enter sin 30 = or some similar sequence of key strokes.
Why do different calculators give different results on different instruments?
There are a few things that can lead to different results on different calculators: Some basic calculators have not been programmed with order of operation rules. So a very basic calculator might show 3 + 5 • 2 as 16, where a scientific calculator will show 3 + 5 • 2 as 13 Some basic calculators do not keep repeating decimals in an internal memory.
What is sin 30 = 1/2?
So sin (30) = 1/2 if your calculator is operating in degrees, but sin (30) = -0.988031624093 if the calculator is operating in radians. You should also check out the settings: it could be set to report answers as fractions (more exact) or as a decimal (often less exact).
What is the difference between scientific calculator and basic calculator?
Some basic calculators do not keep repeating decimals in an internal memory. So basic calculator may show 1/3 as .33333333 then if you take that result and multiply it by 3 it will show 0.99999999, but the scientific calculator will show 1 as the result Why do two calculators show different answers to one math problem?
