Slope of the tangent to the curve

Online Calculus Solver.

The "tangent line" is one of the most important applications of differentiation. The word "tangent" comes from the Latin word "tangere" which means "to touch". The tangent line touches the curve at a point on the curve. So to find the tangent line equation, we need to know the equation of the curve which is given by a function and the point at which the tangent is drawn. Let us see how to find the slope and equation of the tangent line along with a few solved examples.

Slope of the tangent to the curve

First take the given input value, x, and substitute it into the function to find the corresponding output value, y. You now have the point of tangency. Now you can solve this equation for b, the y-intercept. How do you find the slope of the tangent line to a curve at a point? Calculus Derivatives Tangent Line to a Curve. AJ Speller. Sep 13, Second, find the expression that describes the derivative of the function by differentiation. Please see the video example. Video example. Related questions How do you find the equation of a tangent line to a curve?

Maths Program.

Find the slope of the line at the point. Find the slope of the following expression at the point. One way of finding the slope at a given point is by finding the derivative. In this case, we can take the derivative of y with respect to x, and plug in the desired value for x. Thus our slope at the specific point is. To find the slope of the tangent line of the function at the given value, evaluate the first derivative for the given.
