Find the lines that are tangent and normal to the curve y=2 tan(πx / 4) at x=1 . Support your an

step 1 So we need to do two things to find the tension line and the second one will be the normal line

Find the lines that are tangent and normal to the curve y=2...

Key Concepts

Derivative

The derivative of a function provides the instantaneous rate of change at any given point on its curve, effectively giving the slope of the tangent line at that point. It is calculated using limits and is central in understanding how the function behaves locally.

Tangent Line

A tangent line to a curve at a specific point is a straight line that touches the curve only at that point and has the same slope as the curve at that point. This concept is used for approximating the function near that point and is derived using the value of the function and its derivative.

Normal Line

The normal line at a point on a curve is defined as the line perpendicular to the tangent line at that same point. Its slope is the negative reciprocal of the tangent’s slope, and it represents the direction in which the function is not changing most rapidly.

Graphical Interpretation

Graphical interpretation involves plotting both the original function and the lines (tangent and normal) on the same coordinate system. This visualization helps in validating that the tangent touches the curve precisely at one point and that the normal is perpendicular to this tangent, reinforcing the analytical findings.
