SUMMARY

The discussion centers on algebraic manipulation to isolate variables in the equation A = 1/2 B (C - D) ^2. The correct formulation for making B the subject is B = (2A) / (C - D) ^2. Additionally, to isolate D, the equation can be rearranged to D = C - sqrt(2A/B). For making C the subject in A = B / (C x D x E) x gradient, the correct expression is C = B / (A x D x E).

PREREQUISITES

Hi.

A = 1/2 B (C - D) ^2

And I wanted to make B the subject

I have done:

2 x B = (C - D) ^ 2 / A

B = ( (C - D ^ 2) / A) / 2

Is this correct or not? And if not could you please amend it to make B the subject?

These are not the actual variables in the question by the way.


Also, how would I make D the subject in:

A = 1/2 B (C - D) ^2

Any help is appreciated. Thanks.

And one last question,
How would I make

C the subject in:

A = B / ( C x D x E) x gradient?
 
Hi questions_uk! :smile:

(try using the X2 tag just above the Reply box :wink:)
questions_uk said:
A = 1/2 B (C - D) ^2

Do you mean A = B(C - D)2/2,

or A = (C - D)2/2B ? :confused:
 
Hi.

From A = 1/2 B (C-D)2

And making B the subject.
 
When someone asks for clarification, do NOT just repeat the original post!

Please answer the question! Is that
A= 1/(2B(C-D)^2) or A= (1/2)B(C-D)^2 ?
