Draw argand diagram

Modulus=|z|= length of the line

So |z|=(x²+y²)^0.5

Argument=Angle between real (x axis) and line

so arg(z)=arctan(y/x)

The “PAC” acronym stands for “Political Action Committee”, with PACs being significant aspects of the campaign finance aspects of the political system within the US. Regular PACs are subject to spending l...

Integrate by parts: integral = [uv] - ∫u'v dx (u'= derivative of u, v'= derivative of v)

u= x     u'= 1

v' = sin2x        v= -0.5cos2x

= -0.5xcosx  -  ∫-0.5cos2x dx

= -0.5xcosx...

Integrate, y= 3x² -1/x

 1{³ 3x² - 1/x dx = [x-lnx]³₁= (3-ln3)-(1-ln1) = 3-ln3-1+0= 2-ln3
