Hi everyone.

I was hoping somebody could please give me some guidance on transposing a formula using force gravity u sin cos and tan. The u is not really a u, it stands for the coeffficient of friction.

The formula reads; F=umgCostheta - mgCosthetaTan theta

Looking at transposing it to read; (F=mgCostheta(u - Tantheta)

any help appreciated

Thanks

David
