Project activity

○

Bill Foster on Solve a separable first order ODE, 7 years ago

Gave some feedback: Ready to use

○

Bill Foster commented on Transform second order ODE into 2D and 3D dynamical systems 7 years ago

Does not display the correct ODE in the statement when run.

Bill Foster on Transform second order ODE into 2D and 3D dynamical systems 7 years ago

Gave some feedback: Has some problems

○

Bill Foster on Tom 1341cba2b extra 7 years ago

Gave some feedback: Ready to use

○

Bill Foster on The modulus of complex numbers 7 years ago

Gave some feedback: Has some problems

○

Bill Foster commented on The modulus of complex numbers 7 years ago

There is a tolerance of 0,001 for the answers which is very generous as the student should get the square root of a number to 3 dps exactly.

The question is ready for use if this is allowed.

○

Bill Foster on The distance between two complex numbers 7 years ago

Gave some feedback: Has some problems

○

There is a tolerance of 0,001 for the answers which is very generous as the student should get the square root of a number to 3 dps exactly.

The question is ready for use if this is allowed.

Bill Foster on Taylor series (three terms) 7 years ago

Gave some feedback: Ready to use

○

Bill Foster on Transform second order ODE into 2D and 3D dynamical systems 7 years ago

Gave some feedback: Has some problems

Bill Foster commented on Transform second order ODE into 2D and 3D dynamical systems 7 years ago

The expression \[\simplify[std]{ddot:x+{a1}*dot:x+{b1}*sin(x)+{c1}*t^{n1}}=0,\] in the statement when run results in a multiple of ddot:x and no dot:x.
