AP Calculus AB: Lesson 93 Newton's Method Newton’s Method
AP Calculus AB: Lesson 93 Newton's Method Start at x=4 Tangent Line y-f(4)=f’(4)(x-4) Follow it up the graph. x-intercept 0-4.64025=12.187501(x-3.25) x-intercept X=2.86926157 Tangent Line y-f(3.25)=f’(3.25)(x-3.25) Y-intercept 0-18=24(x-4) 4 - .75=x 3.25 = x Y-intercept 0-f(4)=f’(4)(x-4) Step 1: Find tangent line equation, L_1, at point (x_1,y_1) Step 2: Find x-intercept of tangent line, L_1. C Step 3: Find tangent line equation, L_2, at x_2, y_2. Step 4: Find x-intercept of L_2. Call it x_3. Etc. Repeat Steps until x_n and x_(n+1) are almost the same.
