    Suggestions for non-euclidean geometry (analytical) books?

    Hello. I am very well versed in my mathematics(Mary Boas, Mathematical Methods of the Physical Sciences, all problems done, Courant Hilbert, Methods of Mathematical Physics,Real and Complex analysis Walter Rudin) I want an optics text that will assume all knowledge of mathematics but that...

    What is the Normal Force on a Rider in a Ferris Wheel at the Midpoint?

    it is obviously true that the gravity and the acceleration are not acting in the same direction. However, my solution does not imply that they are acting in the same direction. I have put a figure for clarification. The forces acting in the radial direction are mgsinθ and n which are both...

    What is the Normal Force on a Rider in a Ferris Wheel at the Midpoint?

    Homework Statement The original problem is Figure P6.61 shows a Ferris wheel( I have attached the image) that rotates four times each minute. It carries each car around a circle of diameter 18.0 m. (a) What is the centripetal acceleration of a rider? What force does the seat exert on a...

    Conflict normal force in inclined plane

    but if acceleration in the y' plane was not zero, then wouldn't the car have to go through the ramp. my y' axis is perpendicular to the road. Accleration in the y' direction would mean jumping off the road or going into it.

    Conflict normal force in inclined plane

    What I meant was that in the plane x', y' that is inclined at an angle θ so that the axes are parallel to the inclined bank, the y' accleration is zero. Please correct me if I am wrong

    Conflict normal force in inclined plane

    The problem is not with the problem; I knew from the beginning that the solution was as follows \begin{array}{l} {F_r} = {\rm{ - }}n{\rm{sin}}\theta = - \frac{{m{v^2}}}{r}\\ {\rm{and I know that}}\\ n\cos \theta = mg\\ \tan \theta = \frac{{{v^2}}}{{rg}}\\ \theta = \arctan \left(...

    Conflict normal force in inclined plane

    but even if you take the correct first solution where I resolve N into its components,if I find Nsin(theta) in the following way, \begin{array}{l} N\cos \theta = mg\\ {N^2} - {N^2}{\cos ^2}\theta = {N^2}{\sin ^2}\theta = {N^2} - {\left( {mg} \right)^2}\\ N\sin (\theta ) = \sqrt {{N^2} -...

    Conflict normal force in inclined plane

    Homework Statement The original problem was as follows: A civil engineer wishes to redesign a curved roadway in such a way that a car will not have to rely on friction to round the curve without skidding. In other words, a car moving at the designated speed can negotiate the curve even when...

    Looking for a good number theory book(

    Here is my situation, In short I want a number theory book that doesn't assume knowledge of previous number theory but assumes all knowledge of mathematics. I have been knowing multivariable calculus since about 4 years(learned it from Thomas 4th edition(this book was not like the later...
