y=1/2x+2cos(x)+1.25 is sort of close. Matching up those constants is tough but I love the challenge.
I’m close, but not dead on:
y=0.25x + 1.5(cos(2.5sin(.5x))+1.75
Excited to see people leaving their attempts in the comments. Two questions I’m wondering about as this project continues to take shape:
1. Should we share our attempts by writing the equation in the comments, or by linking to a saved Desmos graph? First way is simpler, second way prevents spoilers.
2. For the advanced challenges, should the author post a hint at some point in the day? 12 pm? 3 pm? 6 pm?
Thanks for playing along! I look forward to more contributions from the twitterblogosphere.
P.S. A third question for those with more blogging expertise (especially related to comments): Should comments be more open? Or is a required sign-in a good way to fight spam?
(2) Definitely — especially for the hardest ones. I still haven’t gotten this one exactly (in fact, no one here has). looks like a 4th power of cos to me. with a slope of ~1/3 under it. But I can’t get it to line up…
What are the rules of the games? Are decimals allowed?
Eli, we’re still working out the “rules of game.” I’ll add posts in a day or so for “How to Play” and “How to Contribute” to establish what is allowed in terms of functions, operations, parameters, etc.
As for a hint for today’s, I have a special place in my heart for exponential functions in general and the natural base in particular.
Ooh, I think I got it! https://www.desmos.com/calculator/v95zjh0inp
Got it too! And it’s beautiful. Nice one.
