Which of these is an explicit method of solving initial value problems?

(a) Forward Euler method

(b) Adams method

(c) Trapezoidal method

(d) Midpoint rule

The question was posed to me in an interview for internship.

My doubt is from Transient Flows in section Transient Flows of Computational Fluid Dynamics

Best answer
Right option is (a) Forward Euler method

The best I can explain: The forward Euler method needs the value of the flow variable at the endpoint. Therefore, it cannot be calculated without any interpolation or approximation. This is an explicit method.
