Derivatives of Exponential and Hyperbolic Functions

The video tutorial explains how to find the derivative of the function f(x) = 3 * sinh(x) using two methods: the basic derivative formula and by converting the function to exponential form. The tutorial highlights the use of the chain rule and demonstrates that both methods yield the same result, confirming the derivative as 3 * cosh(x).

What are the two methods discussed for finding the derivative of f(x) = 3 * sinh(x)?

• Using integration and converting to exponential form

• Using the chain rule and product rule

• Using the basic derivative formula and converting to exponential form

• Using the basic derivative formula and integration

What is the role of the chain rule in finding the derivative of hyperbolic sine functions?

• It is not applicable to hyperbolic functions

• It is always necessary to apply the chain rule

• It is used when the inner function is not equal to x

• It is used to simplify the derivative

What is the derivative of sinh(x) according to the basic derivative formula?

• e^(-x)

• e^x

• sinh(x)

• cosh(x)

How is the function f(x) = 3 * sinh(x) expressed in exponential form?

• 3 * (e^x - e^(-x)) / 2

• 3 * e^x - e^(-x)

• 3 * (e^x + e^(-x)) / 2

• 3 * e^x + e^(-x)

What is the derivative of e^x?

• 1

• e^x

• e^(-x)

• x * e^x

When converting to exponential form, what additional rule is applied to find the derivative of e^(-x)?

• Chain rule

• Quotient rule

• Power rule

• Product rule

What is the final derivative of f(x) = 3 * sinh(x) using the exponential form?

• 3 * sinh(x)

• 3 * cosh(x)

• 3 * e^x

• 3 * e^(-x)

What conclusion is drawn from comparing the two methods of finding the derivative?

• The exponential form is more accurate

• Both methods yield different results

• The basic derivative formula is incorrect

• Both methods yield the same result

Why might one choose to write hyperbolic functions in exponential form?

• To find derivatives more easily

• To make integration easier

• To simplify the function

• To avoid using the chain rule

What is the main takeaway from the tutorial?

• Different methods can yield the same derivative

• Hyperbolic functions are complex

• The chain rule is always needed

• Exponential form is unnecessary
