## How do you find the equation of the tangent line using implicit differentiation?

Equation of the tangent line using implicit differentiation

- Take the derivative of the given function.
- Evaluate the derivative at the given point to find the slope of the tangent line.
- Plug the slope of the tangent line and the given point into the point-slope formula for the equation of a line, ( y − y 1 ) = m ( x − x 1 ) (y-y_1)=m(x-x_1) (y−y1)=m(x−x1), then simplify.

## How do you find the equation of the tangent line of a derivative?

1) Find the first derivative of f(x). 2) Plug x value of the indicated point into f ‘(x) to find the slope at x. 3) Plug x value into f(x) to find the y coordinate of the tangent point. 4) Combine the slope from step 2 and point from step 3 using the point-slope formula to find the equation for the tangent line.

## What is the equation of the tangent line calculator?

What is the tangent line equation? The equation of the tangent line can be found using the formula y – y1 = m (x – x1), where m is the slope and (x1, y1) is the coordinate points of the line.

## What is the equation of tangent to the circle?

The tangent to a circle equation x2+ y2=a2 at (a cos θ, a sin θ ) is x cos θ+y sin θ= a. The tangent to a circle equation x2+ y2=a2 for a line y = mx +c is y = mx ± a √[1+ m2]

## What is the difference between normal and tangent line?

The tangent is a straight line which just touches the curve at a given point. The normal is a straight line which is perpendicular to the tangent.

## How many tangents can be drawn at the ends of a diameter of a circle?

two tangents

## Is this statement correct the tangent drawn at the extremities of the diameter circle are parallel?

Answer: According to the question, The tangents are drawn from the extremities of the diameter. Now we know that the tangents drawn from any point on the circumference of the circle are perpendicular to the line drawn from the center of the circle to the point.

## What sort of a quadrilateral is formed by the tangents at the ends of two diameters of a circle?

Square

## What is the perimeter of a quadrant of radius r?

So, for finding the perimeter of the quadrant, we have to take one-fourth of the circumference of the circle. One should also keep in mind that two times the radius of the circle have to be added to on-fourth the circumference of the circle.

## What is the formula for perimeter of quadrant?

Perimeter of a quadrant of a circle = (π2 + 2)r.
