Задание 1: спроектируйте вектор на оси, на плоскости

Задание 2:  преобразовать полярные и сферические координаты в прямоугольные.

A ( b, R ) à A ( x,y )                                    

                                                                                                              Z

X = R*…                                                       X = R*                                              j

Y = R*…                                                       Y = R*

       Y                                                                                    Z =  R*

 

                b

                                                                                                                                       Y

                                                                                         X

                        R                                                                                                       l

                                                X

 

 

Задание 3:  преобразовать относительные координаты в абсолютные

A (x1,y1) à A(x,y)                                         A(x1,y1) à A(x,y)

Y                     Y1                                            

                                                                                                 L2 =X2+Y2 = X12+Y12  

                                                                                  Y

                        dX                             X1             Y1                                            X1

                                                                                                          

                                   dY                                                        L

                                                                X                                                   j         X

 

            X = dX +…                                                    X = X1*…- Y1*…     разница проекций

            Y = Y1 +…                                                    Y = X1*+Y1*…     сумма    проекций
