100 calculus integrals (world record?)

All calculus integration techniques: Integration by parts, DI method, reverse power rule, u-substitution, trigonometric substitution, integration by substitution, integration by partial fraction decomposition, trigonometric integrals, and more. An extreme calculus tutorial by @blackpenredpen 😃 Lars had beaten cancer and he is doing well right now!! : ) Calculus Finisher t-shirt: Try the problems first: Solutions by Jackw11111: Q1 to Q25, myself :0:00 my first time doing 100 calculus integrals in one take! 1, Integral of tan^5(x)*sec^3(x), 2:19 2, Integral of cos(2x)/(sin(x) cos(x)), 5:58 3, Integral of (x^2 1)/(x^4-x^2 1), 8:00 4, Integral of (x e^x)^2, 12:00 5, Integral of csc^3(x)*sec(x), 14:00
