In this STACK Tutorial, you will learn how to create multipart questions with follow-through marking.
Question Variables:
exp:x^3-2*x^2+x;
pt:2;
ta1:diff(exp,x);
ta2:subst(x=pt,ta1);
ta3:remainder(exp,(x-pt)^2);
Question Text:
Find the equation of the line tangent to {@exp@} at the point \(x={@pt@}\).
1. Differentiate {@exp@} with respect to \(x\). [[input:ans1]] [[validation:ans1]] [[feedback:prt1]]
2. Evaluate your derivative at \(x={@pt@}\). [[input:ans2]] [[validation:ans2]] [[feedback:prt2]]
3. Hence, find the equation of the tangent line. \(y=\)[[input:ans3]] [[validation:ans3]][[feedback:prt3]]
