What is the calculus behind it?

ah hah! I figured it out at last, thank you very much for the help.

I either get sin(theta) = 28.85 or another number out of its domain...

Ahhh, I still don't know what I'm doing... The solutions I am getting are out of the domain of sin and I have no idea what to do... can someone please walk me through this?

How can 1/3 multiplied by 3 give us 1 if 1/3 is the repeating decimal .3 to an infinite number of decimal places? If you multiplied 3 * .3 with an infinite number of repeating 3's wouldn't you get .9 with an infinite number of 9's repeating? Why do we say that (1/3) = .3 repeating and when you...

I don't understand how I balance the two torques, how do I find the torque that is produced by the hinge?

HELP - Magnetism Physics Problem! The problem says: A long piece of wire with a mass of .100 kg and a total length of 4.00m is used to make a square coil with a side of 0.100 m. The coil is hinged along a horizontal side, carries a 3.40-A current, and is placed in a vertical magnetic field...

Can someone please help me? I know that the equation T = BINAcos(theta) has to do with it and i can solve the torque to be .0034 Nm without the cos(theta) from the angle that the plane makes with the vertical but I have absolutely no idea how to solve for theta from the information that is...
