How do you find the x value of a tangent line?
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 find the tangent line to the curve at the origin?
Suppose there is a point (x0,y0) that is on the curve y=x3+2. Then that means y0=x30+2. Furthermore, the slope of the tangent line at this point (x0,y0) is given by f′(x0)=3×20=m. Therefore, the equation of the tangent line through this point is given by y=m(x−x0)+y0=3×20(x−x0)+x30+2=3x20x−2×30+2.

How many points does a tangent line touch?
A tangent to a circle is a straight line which touches the circle at only one point. This point is called the point of tangency. The tangent to a circle is perpendicular to the radius at the point of tangency.
At what points do these tangent lines touch the circles?
In Euclidean plane geometry, a tangent line to a circle is a line that touches the circle at exactly one point, never entering the circle’s interior.
