Question

Did the Matlab solver make a mistake?
I fed this equation into the Matlab terminal: syms y v w i s eqn = y/s-i/s == (y^2*w^2/v^2-w^2)^(1/2) sol = solve(eqn, y) ...

Question

My previous question was closed - fair enough - but I am not a student doing homework but 69 years old - and in the past you helped me to solve 7 polynomial
s*x+i = (x^2*v^2/w^2+v^2)^(1/2) wanted that solved for x

Question

how does this equation solve for x? it's the intersection between a line and a hyperbola - hopefully
s*x+i = (x^2*v^2/w^2+v^2)^(1/2)

Question

Hi, I would need the algebraicly solved two equations for X and Y of the intersection points of two circles to write them as algorithms in a graphics language. Thanks
I understand the two circles to be: (x-x1)^2+(y-y1)^2=r1^2 (x-x2)^2+(y-y2)^2=r2^2 to be multiplied out into: (1) x^2-2*...

How do these Python commands have to look in Matlab to calculate A and B and show me the two results?
A = 10+10 B = A+10 print("A =",A) print("B =",B) --- will show me: --- A = 20 B = 30
