• What number raised to itself is equal to 1/2?

  Graphing x^x on desmos.com makes it look as though the value is always greater than 1/2. Source: 10 months ago

• Data Visualization: Sustainable Throughput Per Freight Car

  =) I've posted a link to the desmos.com page with the data that used to create the graph above in the first reply to the post. =). Source: 10 months ago

  It might help to graph the function, for example using desmos.com. Source: 10 months ago

• How did you check your homework if it’s ungraded and there’s no answer key?

  Many answers can be checked numerically, even if only for a special case. There are also some sites that will solve certain types of problems, for example https://www.integral-calculator.com/. Graphing also sometimes helps, desmos.com. Source: 11 months ago

• For the regions bounded by y = 6cosx and y= 1/4x^2 -7

  It might clarify your thinking to plot the two curves on desmos.com. You can also use the plots to check your work. Source: 11 months ago

• How to get diminishing returns tied to a specific number.

  Try playing around with this function on desmos.com and see what you can come up with. Hope this was helpful. :). Source: 11 months ago

• How do I find the area between the two curves written in white? We haven't been taught sinh and cosh yet but this was one of the hw questions. A quick Google and I found some stuff I thought might be useful and noted in yellow. Thanks!

  It might clarify your thinking to graph the two functions (and help to check your work). On desmos.com, you can graph multiple functions in the same graph. Source: 11 months ago

• Math Final - Finished!

  Just go on desmos.com, know a fair bit about functions, and get to making whatever you want. You can put a transparent image on the graph if you need something to trace, just fiddle with it till it works. Source: 11 months ago

• Why is square root function not parabola?

  I wrote this post, because graph creator on desmos.com draws a circle for function x^2+y^2=1, and I thought it shouldn't, because if you'll count x and y separatley (and combine them), you'll get 3/4 of the circle. You can't get that 4th part of the circle, using this approach. On the other hand, equation can be true in the points (-x; -y). So I was confused by all this. Source: 12 months ago

• Does y=x^1/3 have an extreme value at x=0?

  It might help you to graph the equation, for example using desmos.com. If you do that, you will see that on every interval [0,a] there are greater values, and on every [-a,0] there are smaller values. If you simply equate the first derivative to zero, you will find that 0 is an inflection point--not an extreme. Source: 12 months ago

• Need help here!

  You might want to graph f(x), for example using desmos.com. Source: 12 months ago

• Starting Calc first time in College over the Summer, any advice?

  Draw lots of pictures, and practice neat handwriting. Do all of the suggested practice problems. Know your unit circle like you know your own deepest fears. Use graphing tools like desmos.com to graph the original function AND it's derivative on the same coordinate plane and explain the patterns you observe between the two. Source: 12 months ago

• For what values of 𝑟 is 𝑎^𝑟 defined, where 𝑎 is negative and 𝑟 is rational and positive?

  I tried plotting it on desmos.com, but it doesn't look right, so I'm guessing this set only consists of numbers and not intervals:. Source: about 1 year ago

• How do I find the limit as x approaches negative infinity?

  To help understand the problem, you might graph it (for example, using desmos.com) and/or compute a few actual values (for very negative values). Source: about 1 year ago

• Who is teaching the most innovative College Algebra course out there? Any fresh ideas for syllabi that get away from following the strict order of a textbook?

  Check out geogebra.org and desmos.com and find those online communities, and *thank you.* I'm going to be so bold as to assume you want to make the topics make more sense to people than they usually do, and perhaps get more of them passing the courses? Source: about 1 year ago

• Difficult time with a use of L'Hopital's rule

  Also, you can check your answer numerically by computing the values for some x's close to zero. You could also check by graphing the expression, for example at desmos.com. Source: about 1 year ago

• Homework Help

  It might help to graph the equations, for example using desmos.com (you can graph both expressions on the same graph). Both expressions seem to have the same slope at zero, of about 2 units. Source: about 1 year ago

• help pls on algebra ll............

• How crucial is advanced math? What to do if I just don't get it?

  My suggestion is to ignore all the math aspects about it and open desmos.com write "sin(x+k)", click the k and start playing, add 2, multiply by 2 etc. And see what happens. Source: over 1 year ago

• [grade 12 trigonometry] what part of the equation would the zeros be used for

  Since the range of sin() is [-1,1], you might think that one possibility would be to let the transformed y = 4sin(x). However, this would not change the zeroes--the zeroes would still be {0, pi, 2pi,...}, i.e. k*pi, which doesn't fit the second condition given. In order to make the zeroes be k*pi/2, you might try 4sin(2x), so now for a zero value 2x = k*pi. To check this, it might be worthwhile to use a graphing... Source: over 1 year ago

• y=|x^4 - 4x^2 +3|. Local min at x=-sqrt2 and x=sqrt2, local max at x=0. There is no absolute max or min. Am I right?

  You might try graphing it, for example using the tool at desmos.com. You might graph just the polynomial, or use abs() for absolute value. Source: over 1 year ago
