Questions & Answers

Q: What is the derivative of hyperbolic sine (sinh) with respect to x?

The derivative of hyperbolic sine (sinh) with respect to x is hyperbolic cosine (cosh). This relationship is helpful when differentiating functions involving hyperbolic sine.

Q: What is the integral of hyperbolic tangent (tanh) with respect to x?

The integral of hyperbolic tangent (tanh) with respect to x is hyperbolic secant squared (sech²) plus a constant. This formula allows for finding the integral of functions involving hyperbolic tangent.

Q: How does the derivative of hyperbolic cosine (cosh) differ from regular trigonometric functions?

The derivative of hyperbolic cosine (cosh) with respect to x is hyperbolic sine (sinh), unlike the negative sine in regular trigonometric functions. This difference makes differentiating hyperbolic cosine simpler.

Q: What is the integral of hyperbolic cotangent (coth) with respect to x?

The integral of hyperbolic cotangent (coth) with respect to x is negative hyperbolic cosecant squared (csch²) plus a constant. By knowing this, one can find the integral of functions involving hyperbolic cotangent.
