integral of (dx/(coth^2(2x)*sinh^2(2x)) help, thanksss

Integrate (((cos^2(x)*sin(x)/(1-sin(x)))-sin(x))dx thanks

The resistance of 10 ft length of a 20 mil iron wire is 1.8 ohms. What is the resistivity of the iron?

Two resistors, 6 ohms and 18 ohms are connected in parallel and the combination is connected in series with a 2 ohm resistor. Find the current through each of the first two resistors if the current through the 2 ohm resistor is 1.2 ampere. What is the vol...

Three resistance of 8,12, and 24 ohms are in parallel. This combination is in series with another parallel of 10,10, and 20 ohms. The whole combination is then connected to a battery of 16.6 volts. If the current through the 20 ohm resistor is 0.4 amperes...

A 30 ohm resistor is connected in parallel with a variable resistance R and the parallel combination is then connected in series with a 5 ohm resistor, and connected across 120 volt source. Find the minimum value of R if the power taken by R is equal to t...
