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.
Why do engineers use radian mode?
Radians are used in intermediate and advanced mathematics - in preference to degrees or other units for angular measure.
The tan of a 28 degree angle equals?
To get this answer, type in tan(28) in your calculator. It should come out to be about .532. Make sure your calculator is in Degree mode.
How do you solve sin 72 degrees?
1. Be sure that your graphing calculator is in degree mode. 2. Press sin( 3. Press 72, ) 4. Press Enter The calculator shows: .9510565163 5. Round to .95 Answer: sin 72° = .95
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 mode on a calculator?
On many calculators, the MODE key/button is to set the calculator into degrees or radian angle measurment, that is, when you enter a value, it and all further values you enter will then either be understood by the calculator as a degrees or radian value for an angle.
What is the value of sin 49?
sin(49) = - 0.9537526528 ------------------------------In radian mode. sin(49) = 0.7547095802 -----------------------------In degree mode.
Where is the degree button on a Texas Instruments TI-83 plus?
Press MODE and select DEGREE if you want your calculator to be in degree mode in stead of radian mode. If you want the degree symbol, press 2ND ANGLE (above APPS) and choose the first option.
What is the sin pi over 2?
Sine(pi/2) = 1 This is 'Radian' measure of an angle. pi/2 radians = 90 degrees. When you see something like 'Sine(pi/2)' make sure your calculator is in RADIAN mode. ' NOT degree mode.

How do I change the x-axis on my automatic grapher to degrees?
I am assuming your automatic grapher is a scientific calculator. What you do is turn on the calculator, push the "mode" button. Then look through all of the options. You should find one that says "Radian" and " Degrees". Radian is probably highlighted, click on degrees. Now your x-axis is changed.
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.
Why do engineers use radian mode?

How do I know when to use radian mode or degree mode for TI?
If you don't know what radians are, use degrees. If you don't know what radians OR degrees are, it doesn't matter. If you knew what both of these were, you wouldn't have asked this question. If you feel left out about the secret of radians, don't sweat, you will learn in math class when the time comes. If you just can't wait, there is always Wikipedia...
Can you change from native mode to mixed mode?
No, after converting the Exchange organization to native mode, you cannot change back to mixed mode. This is a one-time conversion!
How do you change a flight mode?
Go to settings then on personal and change it to flight mode or normal...
