On slide 3, in the CL code for the table, I’m just trying to give the correct answer as (sqrt(3))/2,-1/2). Unfortunately, I don’t know the correct way to enter an expression involving a square root as code. When I copy and pasted from the desmos calculator, it did not accept the code in the CL. Here is my activity: Terminal Points and Evaluating Trig Functions ⢠Activity Builder by Desmos
I just want this slide to be self-checking to see in the students can enter the correct terminal point a x & y coordinates.
Also, in your note on slide 3, if you want it to actually display -13pi/6, click the square root button. That will start a latex math box. Then, when you type pi, it’ll change to the symbol. It will also allow a stacked fraction.
Thank you for your help. When I put in the code you provided on slide 3 (in the table), then preview and put in sqrt(3)/2 as my entry in the x column and -1/2 as my entry in the y column, the check mark is not showing up. It is still showing up as an x next to “student screen preview.” Here is the link to the slides with the new code: Terminal Points and Evaluating Trig Functions • Activity Builder by Desmos
Oops. When I copied the version with rounding, I left the slash. Take those out and it should work. Also change the 0.866 to 0.865. (I fixed it in the post above.)
Thanks! How can I put something in the code that signals to the student that they got it correct? For instance, I tried this.cellNumericValue(1,1)"=“” and this.cellNumericValue(1,2)=“” but it did not work. Says “correct” expects a Boolean but got a number.
