    Find the exact value of tan 285 deg + cos 75 deg + cot 60 deg

    the question is: find the exact value of tan 285 deg + cos 75 deg + cot 60 deg i tried converting them to radians and got tan 5pi / 12 + cos 5 pi / 12 + cot pi / 3 by "exact value", the question means fractions, not decimals. as far as i know, only the cot part has some special...

    Can the Numerical Value of Sin or Cos be Derived Without a Calculator?

    Assume you are given tan (pi/6). This means sin (pi/6)/cos (pi/6). But my question is, if you are given sin (pi/6) or cos (pi/6), is it possible to derive the numerical value without using calculator? -Thank you in advance.

    Solving for F(x) = 1 / (sec x) + cos x

    problem: Simplify F(x) = 1 / ( 1+tan^2 x)^.5 - cos x :0<x<pi/2 ok the only thing i can think of to substitute in was (1+tan^2 x)^.5 = sec^2 x ... so i got the problem down to 1 / (sec^2 x)^.5 + cos and then become stucks i m thinken i can just say it is...

    Approximations for e^x, sin and cos

    I had a question on a math test which said that you should find an approximation for e^x which is very good for x \approx 0 . First I declared the function f(x) = e^x . We have the interesting thing that f(x) = f'(x) = f''(x) = f'''(x) \ldots \ \forall x . And because of this we have f(0)...

    I used Sin instead of Cos for a triangle.

    I just spent the last half hour trying to find my error in a problem. I checked my physics, my calculations, everything looked fine. It ended up being the simplest mistake I could make. I used Sin instead of Cos for a triangle. What a waste of time, it's the simplest mistakes you have to watch...
