A(0,0)
and i know that AB=4 BC=3 AC =5
BC goes diagonally downward into the direction of the third "quadrant".

how can i find C(x,y) ? thnx

Hi tukilala! Welcome to PF! :smile:

Well, for a start, it's a 3,4,5 triangle …

so the angle at B is … ? :wink:
 


200 degrees

show us how you calculated that :wink:
 
Hello! There is a simple line in the textbook. If ##S## is a manifold, an injectively immersed submanifold ##M## of ##S## is embedded if and only if ##M## is locally closed in ##S##. Recall the definition. M is locally closed if for each point ##x\in M## there open ##U\subset S## such that ##M\cap U## is closed in ##U##. Embedding to injective immesion is simple. The opposite direction is hard. Suppose I have ##N## as source manifold and ##f:N\rightarrow S## is the injective...
