WitrynaInverse hyperbolic functions. If x = sinh y, then y = sinh-1 a is called the inverse hyperbolic sine of x. Similarly we define the other inverse hyperbolic functions. The inverse hyperbolic functions are multiple-valued and as in the case of inverse trigonometric functions we restrict ourselves to principal values for which they can be … WitrynaSo what you have done is apparently wrong. The equality you used is true, the problemes lies elsewhere. In fact when you add the two terms you found : A =\frac{\cos^2x}{\cos^2x+4\sin^2x} B =\frac{\sin^2x}{\sin^2x+4\cos^2x} ...

Witryna1. You can't really take the integral on [ 0, π / 2] since sec 2 x = 1 / cos 2 x is discontinuous at π / 2. So what we really want is. lim θ → π / 2 − ∫ 0 θ sec 2 x d x + lim ψ → π / 2 + ∫ ψ π sec 2 x d x. We have to split the integral up around the singularity. In this case, we have.
