BTW, I worked out the answer my way and MathMate's way and got 36.23666.. (correct to 5 decimals) both ways. MathMate, I haven't seen that formula in 45 years.

I'm not good at counting these things. You really need a math man to answer this; however, I count 9. Maybe Mathmate, Reiny, or Bob Pursley will do this right.

You can check your value of c by using the Law of Cosines, with the original calyues of a, b and C. c^2 = a^2 + b^2 -2ab cos C c^2 = 460.32 +2141.84 -1986.34*0.8436 c = 30.44 That is not what you came up with. There appears to be something wrong with your initial angles. The ...

Try f(x)=(x+2)/((x+4)(x-5)) the term x+2 will give a x-intercept at x=-2, the denominator gives vertical asymptotes at x=-4 and 5. See http://i263.photobucket.com/albums/ii157/mathmate/rational.png

Since it is not specified in the question, we will assume that the equation for v as a function of time is in m/s. Thus v(t)=45(1-(0.804)^t) m/s where t is in seconds. A plot of the graph of v(t) versus t will shed some light. http://i263.photobucket.com/albums/ii157/mathmate/...

you did not follow MathMate's suggestion f'(x) = 5(cosx - xsinx) f'(π) = 5(cosπ - πsinπ) = 5(-1 - π(0)) = -5 , so m = -5 equation: y = -5x + b , but (π,-5π) lies on it, so -5π = -5(π) + b b = 0 equation : y = -5x or using MathMate's...

I differ on Mathmate on the trig function, the wire is not ever horizontal under weight, the wire is sagging, but the principle is the same, the force is magnified greatly. Tension in wire is proportional to 1/sinAngle.

The question requires you to graph the three functions. The x-values given are suggested values, as explained by Dr. Russ. Plot the functions graphically and you will be able to make observations and remarks. Here's my version of the graph: http://i263.photobucket.com/albums/...
