**How does the calculator work?**

Calculators (and computers) combine inputs using electronic components called logic gates. Together, the logic gates enable circuits to add, subtract, multiply and divide the numbers sent to them by transistors. Take the AND gate: If both the signals that arrive at the gate are 1s, then AND sends out a 1.

#### What is fix on calculator?

The Fix command puts the calculator in fixed-point display mode: all numbers will be displayed with a fixed number of digits (0-9) after the decimal, depending on the argument of Fix. This could be useful if you’re trying to display potentially fractional numbers in a limited amount of space.

**How do you fix a calculator that won’t turn on?**

This time do not hold down the DEL key. Remove one of the AAA batteries, press and hold the [on] key for 10 seconds, release, replace the battery, then turn the unit on. Adjust the contrast.

**What is degree mode on calculator?**

To put most models of scientific calculators in degree mode, all you have to do is press “Mode” and then look at the numbers on the screen beside the menu items. Locate the number beside “Deg” or “Degrees” and press it to change the mode of your calculator.

## How do you calculate degrees?

For example, if you know that 4 of the angles in a pentagon measure 80, 100, 120, and 140 degrees, add the numbers together to get a sum of 440. Then, subtract this sum from the total angle measure for a pentagon, which is 540 degrees: 540 – 440 = 100 degrees. So, the missing angle is 100 degrees.

**How do you do sin 1 on a calculator?**

In some calculators, there is no “arcsin,” or “sin-1” button. Instead, you have to push a “shift” or “function” key, then push the normal “sin” button.

**Is sin 1 the same as 1 sin?**

The notation sin-1(x) has been misunderstood to mean 1/sin(x). So sin-1(x) means the inverse sine of x, that is, the function that undoes the sine function. It is not equal to 1/sin(x). The inverse sine function has the derivative shown in “The Correction”.

#### How do you convert sin to degrees without a calculator?

If sin(theta) = x, theta = arcsin(x) = approx x + (1/6) x^3+ (3/40) x^5 + (5/112) x^7 + (35/1152) x^9. Then you will have to change to degrees by multiplying by 180 / pi. Doing all that arithmetic by hand (which would be without a calculator) ?

**What is the reciprocal of sin?**

The cosecant is the reciprocal of the sine. It is the ratio of the hypotenuse to the side opposite a given angle in a right triangle.

**What is Arcsin equal to?**

The arcsin function is the inverse of the sine function. It returns the angle whose sine is a given number. Means: The angle whose sin is 0.5 is 30 degrees. Use arcsin when you know the sine of an angle and want to know the actual angle.
