    identities: sin^2/cosx = secx- cosx

    sin^2/cosx = secx- cosx i dont know what side to simplfy, and how there is a squared on one side and not the other

    identities: cosx/secx - cotx/tanx = cos^2x X tan^2x

    cosx/secx - cotx/tanx = cos^2x X tan^2x i know to combine the bases but im so confused what do i do to make both sides equal

    identities: 1/tanx = cotx/ sin^2x + cos^2x

    i am not sure how to figure this out: it has to be equal to each other and i got stuck: 1/tanx = cotx/ sin^2x + cos^2x i know that I should reduce the harder side, but i dont know how it would end up to be 1/tanx

    factoring 3x^4 - 4x^3 + 7x^2 + 10x - 4

    how do i factor out this problem: 3x^4 - 4x^3 + 7x^2 + 10x - 4 i factored it out to this point: (x + 1)(3x^3 0 7x^2 + 14x - 4) no im lost i tried the rational zero test but nothing work so im really confused

    simplifing X(x/2 + (piex/2)/2 - 10)

    so im supposed to simplify this part of the equation and i am not sure how to do it: X(x/2 + (piex/2)/2 - 10) i got how to do the first and the last part, but the middle i dont really now how to do that one. please help me :cry:

    The area of the window is given by \L\\A=\frac{{\pi}(\frac{x}{2})^{2}}{2}+xy.......[1]- i dont understand what the one is doing on the very end of the equation \L\\2y+x+\frac{{\pi}x}{2}=20........[2] Solve [2] for x and sub into [1]. -what do u mean here It'll then be entirely in terms of...
