bearing journal
tan (theta x theta) : must square the value of the angle, theta, before applying the trig function, tangent.
Interference between journal bearing to bearing housing is called bearing crush.

True
That depends on the value of the angle, theta. csc is short for "cosecans", and is the reciprocal of the sine. That is, csc theta = 1 / sin theta.
No, they cannot all be negative and retain the same value for theta, as is shown with the four quadrants and their trigonemtric properties. For example, in the first quadrant (0
Your question is insufficiently precise, but I'll try to answer anyway. "Sine squared theta" usually means "the value of the sine of theta, quantity squared". "Sine theta squared" usually means "the value of the sine of the quantity theta*theta". The two are not at all the same.
theta = arcsin(0.0138) is the principal value.
putting a journal bearing at each end of the turbine rotor or shaft would be to support it.
engineering application of fitted bearing
Any value for which sin(theta) = 0, i.e. theta = N*180, N being an Integer.
