Radians in calc, degrees in physics (unless given degrees). Except in the physics unit of oscillations/simple harmonic motion. Then you should be in radians.

What was removed from the AP Physics 1 exam?
AP Physics 1 covers the same Newtonian mechanics as AP Physics B plus rotational mechanics. The course used to cover introductory electricity (Coulomb’s Law and simple DC circuits), as well as mechanical waves and sound. These units were removed during the 2020 – 2021 school year.
Is AP Calculus in radians or degrees?
The AP Calculus exam is always in radians (but not the physics exam).
What units are on the AP Physics 1 exam?
- Unit 1: Kinematics.
- Unit 2: Dynamics.
- Unit 3: Circular Motion and Gravitation.
- Unit 4: Energy.
- Unit 5: Momentum.
- Unit 6: Simple Harmonic Motion.
- Unit 7: Torque and Rotational Motion.
Are radians used in physics?
Physics. The radian is widely used in physics when angular measurements are required. For example, angular velocity is typically measured in radians per second (rad/s). One revolution per second is equal to 2ฯ radians per second.
How do you know when to use radians or degree mode?
Eg: if you are calculating sin(30), you should be in degree mode as your angle (30) is measured in degrees. However, if you want to calculate the value of sin(pi/2), then you should be in radian mode since pi/2 is an angle in radians. When you want to graph a trig function, you should be in radian mode.
What is the hardest AP class?
- Chemistry. 56.1% 10.6%
- U.S. Government and Politics. 57.5% 15.5%
- U.S. History. 58.7% 13.0%
- Human Geography. 59.0% 11.8%
- European History. 59.3% 13.7%

- English Literature. 60.1% 9.3%
- World History.
Do you need to memorize the unit circle for AP Calculus?
While you are not required to memorize the tangent values, you will need to be able to calculate them. Recall that tangent = sine / cosine. So, since you will know your cosine and sine values from your unit circle points, all you have to do is divide!
Is there trig in AP Calc?
In AP Calculus you should memorize the six trig function values above. from which we can derive other useful trig formulas. In the AP- world, the answer does not need to be rationalized (Hooray!).
Why do you use radians instead of degrees?
Radians have the following benefits: They are dimensionless, which means that they can be treated just as numbers (although you still do not want to confuse Hertz with radians per second). Radians give a very natural description of an angle (whereas the idea of 360 degrees making a full rotation is very arbitrary).
Is AP Physics 1 or C harder?
We all know that APยฎ Physics 1 is easier than APยฎ Physics C. We note that many of the APยฎ Physics C courses self-select for those motivated students or those with higher grades in Math. That is the reason for the ridiculously high rates for APยฎ Physics C as compared to APยฎ Physics 1.
What is the pass rate for AP Physics?
If scoring a 5 on your APยฎ exams is a goal, you will want to approach APยฎ Physics 1 with caution. This course has one of the lowest percentages of students who scored a 5 in 2019 at 6.7%. The overall passing rate is also lower than average, at 45.4%.
Is AP chem or AP Physics harder?
Based on College Board pass rates, AP Physics 1 is more difficult than AP Chemistry. That said, AP Chemistry is not far behind — AP Physics 1 has a pass rate of about 52% while AP Chemistry has a pass rate of 56%.
Should I have my calculator in radians or degrees for SAT?
A question with angles in degrees needs the calculator to be in degrees, and a question with angles in radians needs the calculator to be in radians. Degrees are more common on the SAT than radians though.
Why do you have to use radians in calculus?
Radians make it possible to relate a linear measure and an angle measure. A unit circle is a circle whose radius is one unit. The one unit radius is the same as one unit along the circumference.
Should my calculator be in degrees or radians for trig?
Any angle plugged into a trig function must be in radians but, because degrees are so common outside of a math class, calculators are designed to handle degrees inside trig functions.
What mode should my calculator be in calculus?
Your calculator should be in radian mode. There are two modes for angles: degrees and radians. Make sure that radians is selected.
What is the difference between a radian and a degree?
A degree is a unit of measurement which is used to measure circles, spheres, and angles while a radian is also a unit of measurement which is used to measure angles. A circle has 360 degrees which are its full area while its radian is only half of it which is 180 degrees or one pi radian.
Why is 360 degrees 2 pi radians?
What AP exam has the lowest pass rate?
Despite a reputation as one of the most difficult AP classes, Physics 1 is also one of the most popularโ137,229 students took it in 2021. Physics 1 has the lowest pass rate of any AP exam (42.1%) along with one of the lowest percentages of students scoring a 5 (just 6.9%).
Which AP is the easiest?

Why do so many people fail AP Exams?
Why are students unprepared? Chakravarty says students are academically unprepared for the difficulty of AP courses, whether they are taking the course too early in their high school career or without the appropriate preparatory courses.
What is a good grade for AP Physics 1?
What is a good APยฎ Physics 1 score? Earning a 3, 4, or 5 is generally accepted as scoring well on an APยฎ exam. As reported by the College Board, a 3 is ‘qualified,’ a 4 ‘well qualified,’ and a 5 ‘extremely well qualified.
What is a 70 on an AP test?
Usually, a 70 to 75 percent out of 100 translates to a 5. However, there are some exams that are exceptions to this rule of thumb. The AP Grades that are reported to students, high schools, colleges, and universities in July are on AP’s five-point scale: 5: Extremely well qualified.
