# Use the given conditions to write an equation for the line in point-slope form calculator

Point slop is one of the method used to find the straight line equation. If f is differentiable at a, then f must also be continuous at a. As an example, choose a point a and let f be the step function that returns the value 1 for all x less than a, and returns a different value 10 for all x greater than or equal to a.

Consequently, the secant lines do not approach any single slope, so the limit of the difference quotient does not exist.

## Polynomial Calculators

However, even if a function is continuous at a point, it may not be differentiable there. If h is positive, then the slope of the secant line from 0 to h is one, whereas if h is negative, then the slope of the secant line from 0 to h is negative one.

Even a function with a smooth graph is not differentiable at a point where its tangent is vertical: Most functions that occur in practice have derivatives at all points or at almost every point.

Early in the history of calculusmany mathematicians assumed that a continuous function was differentiable at most points.

Under mild conditions, for example if the function is a monotone function or a Lipschitz functionthis is true.

However, in Weierstrass found the first example of a function that is continuous everywhere but differentiable nowhere.

## Point-Slope Calculator (Many functions to try!)

This example is now known as the Weierstrass function. InStefan Banach proved that the set of functions that have a derivative at some point is a meager set in the space of all continuous functions.

The derivative as a function[ edit ] The derivative at different points of a differentiable function. In this case, the derivative is equal to:barnweddingvt.com is the place to go to get the answers you need and to ask the questions you want.

Since the point-slope form line is parallel to that, the point-slope form equation must also have a slope of 3/2. Now, let's use point-slope form.

For a line with slope m and that passes through, the point slope form equation is the following. Question Use the given conditions to write an equation for the line in point-slope form and slope-intercept form.

Define the 2-dimensional vector cross product v × w to be v x w y − v y w x.. Suppose the two line segments run from p to p + r and from q to q + barnweddingvt.com any point on the first line is representable as p + t r (for a scalar parameter t) and any point on the second line as q + u s (for a scalar parameter u). Problem 43PE: Write an equation of the line satisfying the given conditions. Write the answer in slope-intercept form (if possible) and in standard form with no fractional coefficients. Write the answer in slope-intercept form (if possible) and in standard form with no fractional coefficients.
