>tfw smart but sloppy
>>16833144You forgot you constant of integration.-2 points.
>>16833144What are you integrating with respect to? [math]\int \sin(x)dx = \cos(x) + C \neq \int\sin(x) dy = y \sin(x)+C[/math]
>>16833920my graduate level analysis book develops lebesgue integration in one variable without ever once writing the differential. only when considering multivariable functions does the author bother.also, learning about exterior algebra and differential forms has given me a different perspective on what d (the exterior derivative) actually means, and you can integrate over differential forms just fine even without a d
>>16833930In that case, you'd write [math] \int \sin [/math] not [math] \int \sin x[/math]
>>16833914>>16833920thank you very much for explaining the point of the OPbtw the antiderivative of sin is -cosretards
>>16833988Maybe his sloppiness was also in forgetting the "h" on both sides, rather than the minus sign.
>Two mathematicians walk into a bar and begin to argue about the intelligence of the waitresses. One mathematician gets up, and on his way to the bathroom stops his server. He tells her: "I'll give you $5 is you answer "one-third x cubed" to the next question I ask you, ok?" The server nods, and walks away. When the mathematician returns to his table, he tells his colleague: "I bet you $100 that our server can answer a simple calculus problem." He then proceeds to flag down the server and asks her, "What is the indefinite integral of x squared?" She responds, "one-third x cubed." The man then proceeds to collect his money, only to be interrupted by the server saying "plus a constant."
>>16833914>>16833999>Muh plus constantThis is only a point that mouthbreathing retards make.
>>16834010Sorry, bub. I don't make the rules.Come back next semester and maybe you'll get a passing grade.
>>16834011As I said, you are very dimwitted.Out of curiosity, what would you say is antiderivative of 1/x?
>>16834012ln(x)+C_1 where x>0ln(-x)+C_2 where x<0The negative and positive halves are discontinuous to one another so there is flexibility to have two entirely different constants.I admit I only know this because I watched a video on the topic a few months ago.
>>16833986I too, read some of chapter 1 of real and complex analysis myself
>>16833988Lmao, you are right. I've published new papers of diff geo methods for signal processing, and still sometimes mix up the order for d sin -> cos, d^(-1) sin -> -cos
