WebbInverse 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 considered as single-valued.

Webb22 nov. 2024 · Explanation: sin(x + π 4) − cos(x) = 0. By the properties of sines and cosines. sin(x + π 4) = cos( π 2 − x − π 4) = cos( π 4 − x) So the equation turns into: cos( π 4 − x) = cos(x) π 4 −x = ± x + 2kπ. π 4 = 0 + 2kπ or π 4 = 2x + 2kπ. 2x = π 4 +2kπ.
