Finding taylor series

use summation from 0 to infinity of (-1)^n (x^2)^n to find a taylor series for arctan x around x =0-Note that, since: sum(n=0 to infinity) [(-1)^n * (x^2)^n] = sum(n=0 to infinity) (-x^2)^n = 1/[1 - (

Find the differential dy for y = (cos^2)x

y = ( cos x ) ² dy/dx = 2 cos x (- sin x ) dy/dx = - 2 sin x cos x dy/dx = - sin 2x-Thank you ---pleased to help.Report Abuse-your question is the same as y = (cos x)^2 so just use ln to solve th

Find the indefinite integral, integral (x^4) - 4x dx

∫ (-4 x+x^4)dx =∫ x^4 dx - 4 ∫ x dx The integral of x is x^2/2: = ∫ x^4 dx - 2x^2 The integral of x^4 is x^5/5: Ans: x^5/5 - 2 x^2 + C

Help with trig identities

How do I prove this: (cscx/cscx - 1) + (cscx/cscx+1) = 2sec^2x. Major test tmrw so any help is appreciated.-I am assuming that the expression is: cscx/(cscx - 1) + cscx/(cscx + 1) = 2sec²x. Since c

What are the values of a and b that make 1 into a root of P with multiplicty 2

Find the values of a andb so that 1 is a root of multiplicty 2 of the polynomial P(x) = x^873 - 2x^401 - 5x^14 + ax^5 - 3x³ + bx -3 This seems a very messy problem. Is there any easy way to solve t
