(ii) obtain a formula for E in terms of M
To obtain a formula for E in terms of M, we need to know the specific relationship between E and M. Without any further information, it is impossible to provide a formula.
However, if we have an equation or a mathematical expression that relates E and M, we can use algebraic manipulation to isolate E on one side of the equation.
Here's an example:
Let's say we have the equation: E = 2M + 3.
To obtain a formula for E in terms of M, we simply need to rearrange the equation so that M is the subject:
E = 2M + 3
Subtract 3 from both sides:
E - 3 = 2M
Divide both sides by 2:
(E - 3) / 2 = M
Now, we have a formula for M in terms of E:
M = (E - 3) / 2
In this case, the formula for E in terms of M would be:
E = 2M + 3
Please provide more information or context so that I can assist you with a specific formula for E in terms of M.
