Which of the following best describes why we can get away with only studying first-order equations. group of answer choices a) we cannot get more accurate than first-order for ordinary differential equations. b) to get higher-order we have to use partial differential equations. c) we can always convert higher-order equations to a system of first-order equations. d) only first-order equations appear in applications. e) it is impossible to solve systems that are not first order.

C) We can always convert higher-order equations to a system of first-order equations.

This answer is self-explanatory: if higher-order equations can be made into a first-order equation, then, the need to learn how to solve higher-order equations could be considered unrquired.

However, this does not mean that people should not learn how to solve higher-order equations, especially those who are interested in pursuing a career in STEM subjects.

And students should also learn how to convert those equations in first place.

heyo, whats up
