I want to calculate an equation with letter and variable.
Now I can get the variable value presented with the letters I used
but I don't know how to change the letters as real numbers.
this is the example
syms x0 y0 x1 y1 x2 y2 a b p q d positive;
[x0 y0] = solve('(x-p)^2+(y-q)^2=d^2','(p-a)*(y-b)=(x-a)*(q-b)')
then I can get the result
but the problem is how to enter the real number value of letters like
a = 1;
b = 2;
p = 3;
q = 4;
d = 5;
then I can get the numerical value of x, y ???
