Is this really the best method? Is the autistic and useless in the real world proof stuff worth looking at? I just want to feel like I'm gaining something conceptually and in my intuitions, not just doing shit I'll forget a day later.

wikihow my dude

felt the same way after calc 2
calc 1 was interesting and had a bunch of applied applications and so I remember a decent chunk of it thats relevant
calc 2 was nothing but weird ass integrals and I forgot most that crap after the exam
Highly doubt I will ever in nature run into a formula where I'll need to know what the integral of sec^58csc^4 is equal to

that sec 58 csc 4 is probably data points along whatever the fuck the scientist or engineer was studying at a job. he will use numberical methods instead of the dumb trig sub to get the area under the curve

>>9091869
without applications you might as well be memorizing digits of pi.

This guy gets it. Look for applications of what you learn.
