The resultant force, R, is related to two concurrent forces, X and Y, acting at right angles to one another, by the formula R^2=x^2+y^2 . Rewrite the formula for Y.
To find the formula for y in the equation: [tex]r^2=x^2+y^2[/tex] First thing we do is we must isolate the y variable [tex]y^2=r^2-x^2[/tex] To simplify our answer is we will square root both of the sides of the equation, [tex]y= \sqrt{r^2-x^2} [/tex] and this will be the formula for the resultant force for y.
