I Can you solve a Disk, Washer, Shell method problem without drawing a graph?

Click For Summary
Solving Disk, Washer, and Shell method problems without a graph is debated, with some arguing that graphs are essential for correctly setting up integrals. While visual aids can help confirm the setup, there are concerns about drawing accuracy leading to errors in the equations used. Skipping the graphing step due to fear of imperfection is seen as an inadequate solution; instead, improving graphing skills is recommended. The analogy of avoiding a shopping list due to poor handwriting highlights the importance of mastering necessary skills rather than bypassing them. Overall, creating a graph remains a crucial step for accurate problem-solving in these methods.

Solving the problem
Is there a way to solve a Disk,Washer,Shell method problem without actually creating a graph?

Isn't the graph just a visual aid to insure you've setup the integrals correctly?

I'm sure it will give you extra points should you get the wrong answer but have visualized it correctly meaning you should do it for that additional reason alone.

Why would you want to not draw a graph?

Because sometimes I may not draw the graph perfectly and may miss which equation is suppose to be subtracted from the other. I had this happen before.

Not wanting to sketch a graph because you might not do it perfectly is a terrible reason. If you have a problem drawing the graph correctly, the solution is not to skip this important step -- it's to learn how to make the graph good enough to be useful.

What you're saying sounds to me like a situation where somebody needs to get a bunch of items at the store, but doesn't want to write down the list of items because of poor handwriting ability.
