Use Definition 2 to find an expression for the area under the graph of f as a limit. Do not evaluate the limit.

23. f ( x ) = sin x , 0 x π

To determine

To find: The expression for area under the graph.

Explanation of Solution

Given information:

The function is f(x)=sinx.

The upper limit is b=π and lower limit is a=0.

State the definition 2 as shown below:

A=limnRn=limn[f(x1)Δx+f(x2)Δx+...+f(xn)Δx]=limni=1nf(xi)Δx (1)

The area A of the region (S) under the graph f of a continuous function is the sum of area of the approximating rectangles.

Calculation:

Find the width of the interval (Δx) using the relation:

Δx=ban (2)

Here, the upper limit is b, the lower limit is a, and the number of rectangles is n.

Substitute π for b and 0 for a in Equation (2).

Δx=π0n=πn

Find the value of xi using the relation:

xi=a+iΔx (3)

Substitute 0 for a and πn for Δx in Equation (3)
