- Homework Statement
- The problem requires interpreting integrals as areas when calculating. ##\int_1^2 (1-2x)dx##
- Relevant Equations
- Are of a triangle is base X height.
Evaluate the integral using the properties of definite integral and interpreting integrals as areas.
##\int_{-1}^2 (1-2x)dx##
I need to see there are two areas and these are the same but one is under x-axis the other is above x-axis so the value of the integral is zero. To see this is difficult to me.
