Visualize the area under a curve using the online graphing tool Desmos. Use the Desmos applet for a definite integral. Use the definate integral tool to explore the area under a curve. Complete the following: Replace the default equation with f(x) =3x^5-2x^3. First, set the limits as a=1 and b=2 (you may need to zoom in or out to see the graph and the shaded region). Then, experiment with a and b both being negative. Then, let a be negative and b be positive (Try using the slider and have a and b as decimals). Take a screenshot of one of the cases (including the right column of input information and the graph with the shaded region). Next, find ^2_1 (3x^5-2x^3)dx and share the steps used to get it. Please show step by step work and a screenshot for one of the cases.
