Question 914035: Starting with the equation: 1/2piFcC=R How would you solve for Fc? pi is 3.414. I can't type the symbol for pi. I know you have to do something to both sides of the equation but I am at a loss. What to I multiply and what do I divide to find Fc? Thanks

Pi is just pi surrounded by the triple braces rendering tags.
Three of these, {
pi

That will look like, pi.

Guessing that you have a formula (1/2)pi*F[c]C=R shown in pure text for the algebra dot com system, rendered as %281%2F2%29pi%2AF%5Bc%5DC=R. Notice very carefully, the asterisk, * is necessary between pi and the F in order for the pi to be rendered as the correct symbol.

You have part of the idea, to do the same thing to both sides of the equation to find F%5Bc%5D. You see F sub c multiplied by some factors. You want the MULTIPLICATIVE INVERSE of those factors.

Multiply the left and right sides of the equation by %282%2F1%29%281%2Fpi%29%281%2FC%29 and then simplify. Do the steps on paper!

Your finished result may be as highlight%28F%5Bc%5D=2R%2F%28pi%2AC%29%29.

This formula was really meant: 1/(2*pi*F[c]C)=R as shown in pure text.
Rendering tags make it 1%2F%282%2Api%2AF%5Bc%5DC%29=R, and now you know what to do to solve for F%5Bc%5D.
Multiply left and right members by F%5Bc%5D%281%2FR%29 and simplify.
