Hi,
I am trying to find a simple way to numerically solve a system of two
equations equal to zero with two unknowns (x_loc and y_loc). Here is a mock
data set and below it, the equations I need to solve.
theta<-c(180,135,90)/(2*pi)
x<-c(0,0,15)
y<-c(20,0,0)
0 =
-sum((y_loc-y)*(sin(theta)*(x_loc-x)-cos(theta)*(y_loc-y))/(((x_loc-x)^2+(y_loc-y)^2)^0.5)^3)
0 =
-sum((x_loc-x)*(sin(theta)*(x_loc-x)-cos(theta)*(y_loc-y))/(((x_loc-x)^2+(y_loc-y)^2)^0.5)^3)
Thanks in advance.
