Use the midpoint rule with the given value of n to approximate the integral. round the answer to four decimal places. int from 0 to pi/2 (2cos5 x) dx, n = 4

Step-by-step explanation:

we are given integral as

n=4

Firstly, we will find delta x

now, we can find mid-point sum

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
