A 900-lb block is being suspended and held stationary by two steel cables as shown. The first cable (to the left of the block) makes a 70 degree angle with the horizontal, while the second cable...
My professor said for this problem to use inverse trig functions, half angle, and double angle identities. Evaluate: tan(2sin-1(4/5)) Please list the answer...
Solve for ALL values of x in the real number system. If an EXACT solution does not exist, round your answers to the nearest hundredth. sin2x = sinx
Solve for x in the interval... 0<x<2π: 3sin2(2x+1)+2sin(2x+1)-1=0 My teacher says there should be 6 answers. I have a TI-84 calculator, so maybe...
One end of a 9.3 foot pole is 13.6 feet from an observer's eyes, and the other end is 17.4 feet from the observer's eyes. Through what angle does the observer see the pole?
