Hey guys, I need an answer to this by tomorrow. I need to know the answer to this question and the working out of it.
Thanks in advance
(a) Find dy/dx if y = 5x^-1/4
(b) (i) Find the equation of the tangent to the curve
y = x^2 - 5x + 7
at the point (1,3)
(ii) Hence find the area of the triangle formed by this tangent, the x axis and the y axis.
