Let's see Anonymous Wed, Nov 9, 2022 12:00:19 No.14971630 [Reply] [Original]

Let's see if sci can do better than high school where I teach.

>>	Anonymous Wed, Nov 9, 2022 12:06:13 No.14971634 Learn to write unambiguous notation, faggot. Parenthesis exist for a reason. You probably mean sin(2020x), and you're just being annoying with too many negative signs. -(3/2 * -1)/(2020) = 3/(4040)

>>	Anonymous Wed, Nov 9, 2022 15:43:30 No.14971901 1? Since cos((3/2)x) = sin(2020x), I think.

>>	Anonymous Wed, Nov 9, 2022 18:07:50 No.14972140 >>14972088 so either you don't know the derivative of cos(x) or you don't know sin(1.5pi)
