- Coefficient of Static Friction = tan (angle of incline)
Homework Statement I am trying to prove that the coefficient of static friction is equal to the tan of the angle of incline (You can find the proof of this from ) I set the angle of incline as my independent variable and had an angle range from 10 to 37 5 degrees After setting the slope to
- Is There a Trick to Remembering the Trigonometric Functions?
hello everyone! I want to know how to verify cos sin tan I always feel confused when i am doing the physics exercises are we always use cos when it is x-axis and use sin when it is y-axis?? I feel so confused
- Propagation of Uncertainty with Angles • Physics Forums
Homework Statement I conducted an experiment which involves measuring two distances (Y and L) and have used tan to determine the angle, then finally calculated the sine of the angles for use in my analysis I have uncertainties in both length measurements and am unsure how to propagate the
- Limit of Arctanx: Why Does \frac {\pi} {2} Make Sense?
I just wanted to know why the limit of arctanx as x approaches infinity is \frac {\pi} {2} It doesn't make any sense to me
- How to tell when to use Cos vs sin in physics
Homework Statement The first problem was " A 50 N crate is pulled up a 5m inclined plan by a worker at constant velocity If the plane is inclined at an angle of 37degrees to the horizontal and there exists a constant frictional force of 10N between the crate and the surface, what is the force
- Did Feynman really use his own trig notations? - Physics Forums
A friend told me that Feynman used his own set of trig notations because he found "sin x" ambiguous Apparantly he replaced it with a \\sigma stretched over the x like a square root He did similar things for the other trig notations as well, but I can't find any of this info anywhere Anyone
- Propagation of uncertainty with tangent function? - Physics Forums
For a lab, I needed to calculate the uncertainty of a refractive index that was found using Snell's law I found an equation online for propagation of error
- Kleppner - Block on wedge with friction • Physics Forums
Homework Statement This is problem 2 17 from Kleppner and Kolenkow, 2nd edition It is the first problem involving friction, and I want to check my reasoning A block rests on a wedge on a horizontal surface The coefficient of friction of the block on the wedge is ##\\mu## Gravity is directed
