# Slope of tangent

First find the derivative of the function. The slope of the tangent line to a curve at a given point is equal to the slope of the function at that point, and the derivative of a function tells us its slope at any point Slope of the tangent at P. The slope of a curve y = f(x) at the point P means the slope of the tangent at the point P. We need to find this slope to solve many applications since it tells us the rate of change at a particular instant. [We write y = f(x) on the curve since y is a function of x Explanation: To find the slope of the tangent line, first we must take the derivative of, giving us. Next we simply plug in our given x-value, which in this case is. This leaves us with a slope of

Anytime we are asked about slope, immediately find the derivative of the function. We should get y' = 3x 2 - 4x + 1. Evaluate this derivative at x = 1, and we get 3(1) 2-4(1) +1 = 3-4+1= 0 • A Tangent Line is a line which locally touches a curve at one and only one point. • The slope-intercept formula for a line is y = mx + b, where m is the slope of the line and b is the y-intercept. • The point-slope formula for a line is y - y1 = m (x - x1). This formula uses This means that the slope of the tangent line is 16.64, and the slope of the normal line is -1/16.64 or -0.06, which is the negative reciprocal slope! Lastly, we will write the equation of the tangent line and normal lines using the point (1,8) and slope tangent slope of m = 16.64 and normal slope of -0.06, respectively Technically, a tangent line is one that touches a curve at a point without crossing over it. Essentially, its slope matches the slope of the curve at the point. It does not mean that it touches the graph at only one point. It is, in fact, very easy to come up with tangent lines to various curves that intersect the curve at other points

Given the slope, we can obtain the equation of the tangent; The condition for a given line to touch a circle is: Distance of the line from the center of the circle, must be equal to its radius.

The tangent line to a curve at a given point is the line which intersects the curve at the point and has the same instantaneous slope as the curve at the point. Finding the tangent line to a point on a curved graph is challenging and requires the use of calculus; specifically, we will use the derivative to find the slope of the curve We know that the tangent line and the function need to have the same slope at the point (2, \ 10). Therefore, they need to have the same slope when x=2. In order to find the slope of the given function y at x=2, all we need to do is plug 2 into the derivative of y. Therefore, the slope of our line would simply be y' (2)=3 (2)^2+4=16 The derivative of a function is interpreted as the slope of the tangent line to the curve of the function at a certain given point.
