WebDec 28, 2024 · Just as points on the curve are found in terms of t, so are the slopes of the tangent lines. The point on C at t = 3 is (31, 26). The slope of the tangent line is m = 1 / 2 and the slope of the normal line is m = − 2. Thus, ∙ the equation of the tangent line is y = 1 2(x − 31) + 26, and ∙ the equation of the normal line is y = − 2(x − 31) + 26.
