anyone know how to solve these problems..
x^2=y^2+233600-966.64*y*cos(z-65.56) ...........................(1)
x^2=y^2+155600-788.92*y*cos((z+30)-59.53) ............................(2)
x^2=y^2+97600-624.82*y*cos((z+90)-50.19) ..............................(3)
@Dhaah,
For starters:
Subtract 2 from 1 and 3 from 1 to get two equations in y and z. Solve each for y and substitute one into the other getting a single equation in z.
Stumble It!
