Does anybody know how to solve this problem? Given the 3 direction vectors emanating from one apex(P0, at the origin), d1,d2,d3, and the corresponding lengths...
Hi! I just joined this group and I have a problem, which I want you to help me solve. I have to prove that in a triangle ABC, if the angle bisector of A meets...
hi, i have a spirolateral problem that i was wundering if ne1 cud help me solve it. find a spirolateral that has at least 5 "leaves" or the 5 repeating...
After beating my head against the wall repeatedly, I decided to come online to find help with my Trig homework. I'm Allison, and currently taking Trig at my...
I'm stuck on the following problem: sin(a) - csc(a) = -cos(a)cot(a) Here is what I've done: On the left side I get: sin(a) - 1/sin(a) --> * both by sin(a) to...
sin(a)-csc(a)=?-cos(a).cot(a) sin(a)-(1/sin(a))=-cos(a).(cos(a)/sin(a)) Multiple both side with sin(a) sin^2(a)-1=-cos^2(a) Multiple both side with -1 ...
Hello ! To Every one ..... Well i need to know about shortest distance b/w two Stright lines .... plz help me also tell me formulas and i'll be kindfull if u...
... What do you mean? You have two lines in a 3D [or more] space, and you want to find the distance between them? Such as line1 = { P | P = A1 + B1 t1 } and ...
I need some help on my hyperbolic geometry... see if you guys can help me out 1) In hyperbolic geometry, prove that given a line l and a point P not on l,...
Find the equation of the set of points P (x, y) which satisfy the given condition. From the equation sketch the graph. P (x, y) is equidistant from the point...
Welcome Is it true that if a point P is in a polygon ABCD then angles: APB+BPC+CPD+DPA>360 ? If yes, how will look the proof? Thank you for any answer Best...
This is true, only if, one of the internal angles of the polygon is a reflex angle, i.e. the polygon is boomerang or "Starfleet Badge" shaped, and one of the...
Hello Thanks for the answer. I have thinked about it, but I still don't know how to proof that three of the angles at p are equal to 360 deg. Can you give me...
Hello Adam, Here is an example of the special case where the sum of the four angles is greater than 360 deg. Construct the following diagram with ruler, pen...
Let Conic(a,h,b,f,g,c):=axx+2hxy+byy+2fx+2gy+c, where Conic==0 is normally plotted and real coeffecients are assumed. In particular, I have an interest in the...
Hi all, I need help in the following proofs: 1) Suppose that 2 perpendicular bisectors of a hyperbolic triangle intersect in a pt P in the upper half plane....
I hope someone can help with this one...I've tried to hunt these calculations down on the web, but became so overwhelmed and confused by so many similar...
... No, it's not clear O:-) Let me see if I get what you want: point to a star, and then hope that the equipment can track the star without the need to enter...
It's obvious that I am explanation-challenged. I'll try it this way: If I know where I am starting, when I manually move the telescope, I'll know where I end...
... Ok, then _if_ you know your latitude _and_ the time between the two observations, it's a solvable problem: The path of each star is a "parallel" in a...
VERY CLOSE!! I would find the two stars for alignment (initialization) purposes - to tell the computer where the scope is currently pointing, but would ...
Hi folks, I am new to this list and very new to geometry. I am a philosophy student at the University of Memphis. At the present I am reading Edmund Husserl's...
OK, I will be the first to admit that I'm totally feeling lost right now in my Calculus class. Integrands have begun to haunt my dreams. That aside, I've...
