    Slope of polar curve

    Find the slope of the polar curve at the indicated point. r=8(1+cos theta) theta=pi/4 I must be doing it wrong because I took the derivative of r and got: dr/dtheta = -8sin theta= -4 radical 2. The answer is 1-radical 2 Whats my error?

    Secant Line Slope Formula

    Im stuck on this problem and don't know what to do. Using the formula for the slope of a secant line passing through two points on a curve f(x+h)-f(x)/h determine this secant line slope formula for the function f(x)=3x^2-5x. Yu must simplify your result algebraically.

    Real World Problem - Integrating Slope Data!

    Hi, I am a bit confused on the meaning of "slope" and the first and second derivatives. I have an inclinometer that measures its angular orientation with respect to pure vertical, and it is traveling on a small cart up a beam that is compressed. The shape of the compressed beam can be...

    How to get a slope?

    Hi all: I have a stupid question: can I get dy/dx from f(x,y)=c without solving it (c is a constant). Can I take partial derivative with respective x for both sides to get dy/dx? More specific, my equation is 1/xy+1/(1-y)=c. Or is there a better way to get dy/dx at two solutions? Thanks! Simon

    Finding an equation that is tangent to a curve and whose slope is a max.

    a) Find an equation of a line that is tangent to the curve f(x)=2cos3x and whose slope is a maximum. b) Is this the only possible solution? Explain. If there are other possible solutions, how many solutions are there? For a.. I know how to find the tangent of a curve at x=something.. but...

    For what x value does the tangent of the graph of f(x) = xe^2x have a slope = 0?

    I said f'(x) = m = 0 = 2xe^2x ---> x = 0/(2xe^2x) = 0 Is this right?

    finding slope

    Given that triangle ABC has points, A(8,2), B(0,6), and C(-3,2), point C can be moved along a certain line with points A and B remaining stationary, and the area of ΔABC will not change. What is the slope of that line? (It says the answer in my book which is -\frac {1}{2})

    Finding the slope given X^5sin(x) when X=.58?

    So I am supposed to find the slope, m I presume. Anyways, I tried to get the derivative using the quotient rule. THat is: (f * 'g) - (g * 'f) So: X^5*Sin(X) (x^5)(Cos(X)) = (Sin(X))(5x^4) But when X=.58 I got a super tiny answer. I believe the answer was 0.3something...
