Use the Following Property of the Definite Integral to Estimate $\int _ { z / 6 } ^ { x / 4 } 4 \sin x d x$

question 40

Short Answer

Use the following property of the definite integral to estimate the definite integral $\int _ { z / 6 } ^ { x / 4 } 4 \sin x d x$ :
If $m \leq f ( x ) \leq M$ on $[ a , b ]$ , then
$$m ( b - a ) \leq \int _ { a } ^ { b } f ( x ) d x \leq M ( b - a )$$
