Find the derivative of cos2(2x+3)+4sin x.
Find the derivative of cos2(2x+3).
Find the derivative of 4x5-2xcos(ex2).
Find the derivative of 4xcos(ex2).
The data in the Master folders is “permanent.” The only regular changes are to the assignment dates.
Each 106A class file is used for one section only. All assignments are inherited. Students register for their
10 questions, 8 correct to pass
2. Products 3. Quotients 4. Compositions
5. Compositions of compositions
6. Products with a composite factor
7. Compositions of products
8. Quotients with an embedded composition
9. Quotients with an embedded product
10. Functions defined by equations
X=t,u,v,w,x,y,z; A,C,N>0; B≠0; K≠0,1
F=sqrt(P),sqrt(S),sqrt(T), SN,TN,lnQ,lnCS,eQ,eCS, sinQ,cosQ,sinU,cosU
38templates, each with 7independent variables
and at least one parameter
Success rates should be 40-90%.
Best learning comes from success that builds on previous success.
Topic: derivatives of quotients with powers of trig functions
Find the (exact) x coordinate of the global minimum of f(x)=3x3+bx2+cx on [-1,1].
global min at critical point
global min at endpoint
Students must complete each question successfully, on any number of attempts.
Principal benefit: Students repeat only those questions they get wrong.
Sessions can be given a hierarchical structure.
% of students who complete
2 pts out of 600 – 75% completion
<1 pt out of 700 – 30% completion
0 pts – about 2% completion
% of course grade per assignment
