Find the equation of the tangent to the curve y = x√x at the point (4,6).

Simply the equation. y = x√x is the same as y = x 3/2 . This is because the square root of any articular number is the same as saying that number raised to the power half. Now to do x 1 multiply x 1/2 we sim...

a) Integrate ln(x) + 1/x - x to find the equation for Curve A b) find the x coordinate on Curve A when y = 0.

a) Integrate ln(x) by parts: u = ln(x), dv/dx = 1, du/dx = 1/x, v = x int(u dv/dx) = u v - int(du/dx * v) = ln(x)/x - x so int(ln(x) + 1/x - x) = ln(x)/x - x + ln(x) + x^2 + Cb) y = ln(x)/x - x + ln(x) + x^2...
