Calculus (repost)
Use implicit differentiation to find dy/dx if cos xy = 2x^2 - 3y. I'm stuck on this problem because I'm getting thrown off on how to factor this. Here's my work so far: -{[(dy/dx)y + y]sin xy} = 4x - 3(dy/dx) -{[(dy/dx)y + y]sinxy} + 3(dy/dx) = 4x ...now what? Thx

I have a Pressure in atm and a volume in liters how do i find the temperature in kelvins?? I know the formula pv=nRT works...but i don't know the number of moles so... I don't know what to do.

never mind. I made a silly error. i got .01804 moles...multiplied that times 4.03grams and then multiplied that times 1000 and got 72.7mg. got it! thanks so much!

Physics
so i got the answer to be .01804 moles and i know one mole of helium is 4.03 g do i just multiply the two together? and then divide by 10000 to convert g to mg?

doesnt that give me an answer in moles? ...is there a way to convert moles to mg?

I guess i can try to clear it up. Sorry. So I'm adding the exponents of 1 for EACH variable/base x. That'd make it x^2. Okay, so if i have to rewrite the equation with just one exponent, then would i put the x^2 after JUST ONE of the coefficents? Like this: 4x^2(3) or ...

If i have two base variables with exponents for example: 4x(3x) After getting x^2-would i have just ONE variable base? i.e. 4(3x^2) or place the exponent on BOTH variable bases like this: 4x^2(3x^2)? Thanks!
