Calculus is bullshit, like wtf do you mean the derivative of ((e^-x)cos^2(x))/((x^2)+x+1) is ((e^-x)cos^2(x))/((x^2)+x+1)(-1-(2sinx/cosx)-((2x+1)/(x^2)+x+1))?

俺「1-2sinx」←これをゼロにするxを求める式の途中式 nk「-2で囲った方がわかりやすいからそうしろ」 俺「-2(-1/2 +sinx)」 nk「入れ替えて」 俺「-2(sinx - 1/2)」 ━━━━━━━━━━━━ 友達「-2(-1/2 +sinx)」 nk「まぁ入れ替えた方がいいけどいいよ」 ━━━━━━━━━━━━ ???

#今日積分しました sinx-2(sinx)^2=sinx(1-2sinx)で、0≦x≦π/2ではsinx≧0、1-2sinxは0≦x≦π/6までが正、π/6≦x≦π/2が負 与式=∫[0→π/6]sinx-2(sinx)^2dx+∫[π/6→π/2]-sinx+2(sinx)^2dx =∫[0→π/6]sinx-(1-cos2x)dx+∫[π/6→π/2]-sinx+(1-cos2x)dx =…

integral(sqrt( 1+ 2sinx/2cosx/2)dx) = integral (sqrt(sin²x/2 + cos²x/2 + 2 sinx/2cosx/2)dx) = integral(sqrt(sinx/2 + cosx/2)²dx) = integral (sinx/2+cosx/2)dx = -2cosx/2 + 2 sinx/2 + c

Take 2sinx as an example: if we write 8÷2sinx, it appears very weird to take this as (8÷2)sinx. That would imply that the correct way to write the other interpretation would be 8÷(2sinx), but it contradicts the fact that implicit multiplication is used to get rid of parentheses.

I just did a math exam without a calculator since my prof said it wasnt needed and i had to solve [x- (x^3-2sinx)/(3x^2-2cosx)] - ([x- (x^3-2sinx)/(3x^2-2cosx)])^3 - 2sin{[x- (x^3-2sinx)/(x^2-2cosx)]} / (3 [x- (x^3-2sinx)/{(x^2-2cosx)]^2 -2cos [x- (x^3-2sinx)/(x^2-2cosx)]} if x=2
