Why doesn’t the iPad have a calculator?
Apple never developed a calculator app for iPads that Steve Jobs liked or was satisfied with. Jobs wanted the calculator to be a special item on iPads and some reason the software design team just never came through on this. So, Apple never released a calculator for iOS for iPads.

How do you know when to use radians or degree mode?
If there is a degree symbol, ∘, then use degree mode. If there is no degree symbol, then use radian mode. Even if there is no π in the number.
What’s the difference between deg and rad?
On a scientific calculator “D” or “DEG” means the current angle mode is in degrees. A degree is a complete revolution of 360 or you could say it is 1/360 of the circumference of a circle. Another is “R” or “RAD”; it means the current angle mode is in Radian.
What does RAD mean in math?
Since radian measure is the ratio of a length to a length, the result is a pure number that needs no unit symbol. Most mathematicians do not write a unit attached to this ratio, although some people add the unit “radians” (symbol: “rad”), to indicate an angular measure, or length along a unit circle.
Why is 180 degrees pi?
It’s because the circumference of a circle is 2pi x r. If you draw a circle of radius 1 unit (1cm, 1 inch, or 1 anything else), and then measure the length of an arc of 180 degrees (ie. a semi-circle), the length of the arc will be pi units (pi cm, pi inches, or pi whatever unit you’re using).
Are degrees dimensionless?
Angles measured in radians are considered to be dimensionless because the radian measure of angles is defined as the ratio of two lengths θ=sr (where s is some arc measuring s-units in length, and r is the radius) however the degree measure is not defined in this way and it is said to be dimensionless too.
How pi radians is 180 degrees?
Radians and Degrees
| Degrees | Radians (exact) | Radians (approx) |
|---|---|---|
| 45° | π/4 | 0.785 |
| 60° | π/3 | 1.047 |
| 90° | π/2 | 1.571 |
| 180° | π | 3.142 |
How many degrees are in a circle?
360
What is 180 degrees in a circle?
A Full Circle is 360° Half a circle is 180° (called a Straight Angle) Quarter of a circle is 90° (called a Right Angle)
What angle is 45?
An angle can be measured using a protractor, and the angle of measure 90 degrees is called a right angle. In a right angle, the two arms are perpendicular to each other. When the right angle is divided into two equal parts each angle measures 45°.
How many 45 angles does it take to make a full turn?
Eight 45
How do you get 45 degrees?
45 Degree Angle
- Construct a perpendicular line.
- Place compass on intersection point.
- Adjust compass width to reach start point.
- Draw an arc that intersects perpendicular line.
- Place ruler on start point and where arc intersects perpendicular line.
- Draw 45 Degree Line.
