Seriously! I took trig and nobody ever said "Here's a picture of a circle. Here's what cosine, sine, and tangent are".
I had no clue what those concepts were for at least a year, but I managed because I always knew I could take both sine and cosine and say "well I need the bigger number in this scenario ∂or the smaller one in that one, so it must be (cos or sin)"
When I saw a picture of a circle and an angle that basically said "Cosine is how far you are horizontally and sine is how far you are vertically" it was so damned simple I hated that I hadn't learned sooner. How did I miss it? Was I sick that day?
- jononor 8y agoMaybe we should have 'intuition checks'? A kind of test (not graded) that regularly checks that key intuitive concept have been learned? Like show a circle and ask to place the sin,cos..
