Homework Equations
y = sin^3t and dy = 3cos^2t sint dt. Shouldn't there be a Minus Sign there?
The Attempt at a Solution
Answer is correct. But isn't there a missing Minus Sign?
What makes you think that? Shouldn't it be ##3sin^2tcostdt##?Homework Statement

Shouldn't that be "##3 \sin^2{t} \cos{t}\ dt##" ?dy = 3cos^2t sint dt. Shouldn't there be a Minus Sign there?
I don't understand the notation "x-=". You didn't say where the minus sign is missing.The book has x-=cos^3 t and dx = 3 cos^2 t sin t dt That's where the minus sign appears to be missing.

Hello Daniel McKinley. Welcome to PF !The book has x-=cos^3 t and dx = 3 cos^2 t sin t dt That's where the minus sign appears to be missing.
