### Write an equation of the tangent line to the curve given by y=(lnx)^lnx, at x=e.

let u = ln(x).  Then for y = ln(x)^ln(x) we have y=u^u and the chain rule gives us dy/dx=dy/du*du/dx Assume u>0 (there are problems otherwise) then ln(y) = ln(u^u) =ln(u)*u Differentiate both sides using chain rule on the left and product rule on the right dy/du*1/y = ln(u)+1/u*u=ln(u)+1

### (sin x + sin 2x + sin 3x - sin 4x)/ (cos x + cos 2x + cos 3x + cos 4x) =

Should all the signs be positive?  I'll assume initially there are all pluses, so we have: (sinx+sin2x+sin3x+sin4x)/(cosx+cosx+cos3x+cos4x). The shortcut is to use the identity: sinA+sinB=2sin((A+B)/2)cos((A-B)/2) and cosA+cosB=2cos((A+B)/2)cos((A-B)/2). sinx+sin4x=2sin(5x/2)cos(3x/

### sin3x + sinx/cosx + cos3x= tan2x

sinA+sinB=2sin((A+B)/2)cos((A-B)/2); cosA+cosB=2cos((A+B)/2)cos((A-B)/2). If A=3x and B=x, sin3x+sinx=2sin2xcosx; cos3x+cosx=2cos2xcosx. Therefore (sin3x+sinx)/(cosx+cos3x)=2sin2xcosx/2cos2xcosx=tan2x QED.
