## How do I find the tangent line of a circle?

A tangent to a circle at point P with coordinates is a straight line that touches the circle at P. The tangent is perpendicular to the radius which joins the centre of the circle to the point P. As the tangent is a straight line, the equation of the tangent will be of the form y = m x + c .

## How do you find the tangent?

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.

## How do you calculate a tangent?

In order to find the equation of a tangent, we: Differentiate the equation of the curve Substitute the value into the differentiated equation to find the gradient Substitute the value into the original equation of the curve to find the y-coordinate. Substitute your point on the line and the gradient into.
