Free slope calculator - find the slope of a line given two points, a function or the intercept step-by-step This website uses cookies to ensure you get the best experience. Square root is discontinuous across its branch cut along the negative real axis: Sqrt [x ^2] cannot automatically be reduced to x: With x assumed positive, the simplification can be done: Use PowerExpand to do the formal reduction: Along the branch cut, these are not the same: If neither A nor B is Inf, but one or both inputs is NaN, then hypot returns NaN. Inputs A and B must either be the same size or have sizes that are compatible (for example, A is an M-by-N matrix and B is a scalar or 1-by-N row vector).
