intergral of (x^3 4x + 3)/(2x) dx
would this be ln abs(x^34x+3) + C?
I don't really understand how to solve this problem.
d/dx (tan (x^2))
sec^2(x^2)(2x)
would this be the correct answer to find the derivative of tan (x^2)?
no, because if you differentiate your answer you don't get what you started with.
divide the 2x into each term so that your expression becomes
(1/2)x^2  2 + 3/(2x)
now the integral of that is
(1/6)x^3 + 2x + (3/2)lnx + c
yes, to your derivative of tan x^2

would this be a correct proof of the cauchyschwartz inequality: abs=absolute value abs(u*v) is less than or equal to abs(u)*abs(v). Then you divide both sides by abs(u)*abs(v) so that you get cos(theta) is less than or equal to 1.

So I am suppose to evaulate this problem y=tan^4(2x) and I am confused. my friend did this : 3 tan ^4 (2x) d sec^ 2x (2x)= 6 tan ^4 (2x) d sec^2 (2x) She says it's right but what confuses me is she deriving the 4 and made it a three?
