As for how you can take the hyperbolic cosine of an imaginary number, well Euler's formula says e^(ix) = cos(x) + i sin(x). You can find a number of pages on-line that show the derivation of this. And if you mean the general anti-derivative of cos(x 2), it is not an "elementary" function.That is, it cannot be written in terms of functions you normally learn (polynomials, rational functions, radicals, exponentials, logarithms, trig functions. I want to simplify this expression to contain 2 or fewer terms. Is this possible, and if so, what are the steps I can take to do so? sin x / ( 1 + cos x ) This is the Maclaurin series for cos x.

Your first integral is correct. The second has two sign errors: u = \cos x \implies du = -\sin x\,dx So evaluating the second integral should yield \begin{align} \int

Derivative of cos x. What is the speciﬁc formula for the derivative of the function cos x? This calculation is very similar to that of the derivative of sin(x). If you get stuck on a step here it may help to go back and review the corresponding step there. As in thecalculation of. d sinx, we begin with deﬁnition derivative: dx. d. cos x
