Chapter 2: Q 37. (page 237)

Fill in the blank:

ddx(sinh-1x).

Short Answer

Expert verified

ddx(sinh-1x)=1x2+1.

Step by step solution

01

Given Information 

The given expression is ddx(sinh-1x).

02

Simplification 

We know that

sinh-1x=lnx+x2+1.wecomputethederivativeofsinh-1x.ddx(sinh-1x)=ddx(lnx+x2+1=1x+x2+1{1+12(x2+1)-12(2x)}=1x2+1Therefore,ddx(sinh-1x)=1x2+1.

Find the derivatives of the functions in Exercises 21–46. Keep in mind that it may be convenient to do some preliminary algebra before differentiating.

f(x)=x(3x2+1)9

Use the definition of the derivative to find the equations of the lines described in Exercises 59-64.

The line that passes through the point (3,2)and is parallel to the tangent line to f(x)=1x at x=-1.

For each function f(x)and interval localid="1648297458718" a,bin Exercises localid="1648297462718" 81-86, use the Intermediate Value Theorem to argue that the function must have at least one real root on localid="1648297466951" a,b. Then apply Newton’s method to approximate that root.

localid="1648297471865" f(x)=x3-3x+1,a,b=1,2

Use the definition of the derivative to find the equations of the lines described in Exercises 59-64.

The line that is perpendicular to the tangent line to f(x)=x4+1at x=2 and also passes through the point(-1,8)

In Exercises 69–80, determine whether or not fis continuous and/or differentiable at the given value of x. If not, determine any left or right continuity or differentiability. For the last four functions, use graphs instead of the definition of the derivative.
