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

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

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

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

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

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 question is: a norman window has a shape of a rectangle surmonted by a semicircle of diameter equal to the width of the rectangle. if the perimeter of the winder is 20 feet, what dimensions will admit the most light(maximize area)? i have no idea what it means and also says to express the...

what is the answer or the long divison problem: X^5-X^4-5X^3+X^2+8X+4 / X^4-2X^3-8X^2+18X-9

How would I factor out this expression? X^4 - 2X^3 - 8X^2 + 18X - 9

how do you factor out y= x^2 - 3x 2

i dont understand how to find any asymptotes with this equation: f(x) = (x^5 - x^4 + x^2 + 8x + 4) / (x^4 - 2x^3 - 8x^2 + 18x - 9)
