Hi! Please help :-) Find an equation for the circle of the curvature of the curve r(t) = ti + (sint)j at the point (pi/2, 1) (The curve parametrizes the graph of y = sinx in the xy-plane)

The curve y = x/(1 + x^2)is called a serpentine. Find an equation of the tangent line to this curve at the point (4, 0.24). Round the slope and y-intercept to two decimal places.)

I will assume you want the area between the curve and the x-axis. Under the curve would be infinitely large, it would be open below. area = ∫ x^2 + x) dx from 0 to 3 = [(1/3)x^3 + (1/2)x^2 ] from 0 to 3 = 9 + 9/2 - 0 - 0 = 27/2 square units

suppose that the area under the curve y=1/x from x=a to x=b is k. the area in terms of k, under the curve y=1/x from x=2a to x=2b? justify

when finding the area to the left of the Z score and Z= 1.43 do i subtract the z score from one or is that only when finding the area to the right of Z

last calc question, i promise!
given the curve x + xy + 2y^2 = 6... a. find an expression for the slope of the curve. i got (-1-y)/(x + 4y) as my answer. b. write an equation for the line tangent to the curve at the point (2,1). i got y = (-1/3)x + (5/3). but i didn't any answer for c! c. find the ...

CALC
Consider half of the rectangle which lies completely in the first quadrant. The lower left corner is the origin (0,0), and the upper right corner lies on the curve y=9-x². The area of the (half) rectangle is therefore: A(x) =x*y =x*(9-x²) =9x-x³ Differentiate ...
