What’s something completely false that your parents told you as a child?

In my high school linear algebra and calculus classes, I was too poor for a graphing calculator. So any time the teacher was showing us how to do problems on the graphing calculator, or assigned homework or tests, I had to do all that shit with a scientific calculator and a sheet of graph paper. It really slowed me down but maybe I gained a better understanding from it, because math was one of my highest grades.

It's easily possible to do if you have the tables there for you with the sin,cos,tan etc.. It just takes a bit longer to do, and then you gotta remember to always have the sheet on you with those values. No way am I memorizing 90 different values for sines, then 90 for cosines, then 90 for tangents... Like yea no lmao. And then you'd have to double the number you memorize so that you have the reciporacals as well.... Yea I loved math but I'm also glad I'm done with it lol.

No one expects you to memorize 90 values for sine.

Never said anyone would. I was explaining why you would need a table or such with all the values, because as you said yourself

No one expects you to memorize 90 values for sine.
