Find the point on the line 4x+3y–6=0 which is closest to the point (–4,1).
I asked a question earlier about open and closed intervals, so why did my teacher say this was wrong? Determine any values of c in the interval [0,2pi] for which f'(x) = 0. f(x)...
An example in my textbook goes as follows: f(x)=ln e3x = 3x f'(x) = 3 I understand that the derivative of 3x is 3, that the derivative of ex is ex, ,and...

A water trough is 6 m long and its cross-section is an isosceles triangle which is 60 cm wide at the top, and the height is 30 cm. The trough is not full. Give an expression for V, the volume of water...
i dont know how to deal with e and sine in the same equation.
i dont understand this at all!! help me with this asap!!
before using differentiation, do I have to FOIL the problem first? i need help.
the might be the most confusing question for me, in my opinion.
Write an equation for the line tangent to the curve f(x) = 4ex - 7 at x = ln 3 Could someone please explain how I might go about answering this question? Thank you!
(a) 6√x-4x3 +5ex (b) πx2
csc = cosecant confusing!!
Differentiation. i need help with this problem.
Find the derivative of f(x)=xsquared(2x-3)to power of 4 sorry i couldn't write the powers out on my phone. Can someone please explain the question?
A small piece of string that measures 20cm in length is cut into two pieces. The first is made into a circle with radius 'r ' in (cm) and the second a square with side length 's' in (cm). Write...
How high should the pole be if the perimeter around the enclosure is to be most brightly lighted? We know that illumination is inversely proportional to the square of the distance from the source...
differentiate the equation. and show workings Y= 3X4 (X2 +2)
Find the derivative of f(x) = x2e–x I've managed some of the question but am having trouble finishing it. Can someone please explain?
