Three long wires are situated in a plane with equal separation. A current of 1A, 2A, 3A flows through these wires in the same direction. What is ratio of F_(1)//F_(2) ? Where F_(1) & F_(2) are force per unit length on the wire 1 and 2 respectively:

If the function f: R to R defined by f(x)=(4^(x))/(4^(x)+2), then show that f(1-x)=1-f(x), and hence deduce the value of f((1)/(4))+2f((1)/(2))+f((3)/(4)) .

Using elementary transformations, find the inverse of the matrix: A = {:[(8,4,3),(2,1,1),(1,2,2)] and use it to solve the following system of equations: {:(8x+4y+3z=19),(2x+y+z=5),(x+2y+2z=7):}
