sec ^-1(x)=an angle, for our case, theta, Lets use the unit circle and basic definitions to determine...z Cos = x/z Tan = y/x and using the trigonometric identities Csc = 1/sin Sec = 1/cos Cot = 1/tan we get Csc = z/y Sec = z/x Cot = x/y So, to answer...

As an SEC fan and supporter, I agree. I believe that the Big Ten... know that college football is cyclical. The time will come for the SEC to have an unimpressive conference, too, once the rest of the country begins to stop...

The SEC touts as its mission statement, “…to protect investors, maintain...good because many of us need all the help we can get. As a part of the SEC ’s mission the belief is that in order to sustain and advance economic growth, capital...

well SEC 2007? Auburn has talent.. possibly the most in the conference.. but... to 8-4 in defense of their title.. AU wins SEC in a classic championship game 34-31 in OT

The SEC is dominant in college football. But I draw the line at ... or Arizona State are much better. SEC players are great in football and will likely win again next year. ...

sec (2x) = 1/cos(2x) The period of cos (2x) can be found using... In this case B = 2. So the period of cos(2x) = period of sec (2x) = 2pi/2 = pi or 180 degrees The amplitude is defined...

tan(x) + sec (x) = 2cos(x) Change everything to sines and cosines... work, by plugging them into the original. tan(x) + sec (x) = 2cos(x) Test x = pi/6: tan(pi/6) + sec (pi/6) = 2cos(pi/6...

∫ sec ^4 (x/2) dx = ∫ sec ^2 (x/2) * sec ^2 (x/2) dx = ∫[1 + tan^2 (x/2)] * sec ^2 (x/2) dx = ∫ sec ^2 (x... tan(x/2) = u for the second integral => (1/2) sec ^2 (x/2) dx = du => sec ^2 (x/2) dx = 2du => Integral...
