= 1 / sin x · 1 / cos x - sin x / cos x = 

= 1 / sinx cos x - sin² x / sin x cos x = 

= ( 1 - sin² x ) / (sin x cos x) =

=  cos² x / ( sin x cos x ) =

Please do step by steps for each!
Schach [20]

Answer:

  • x² - 8x + 12
  • x³ + 2x² - 15x - 36
  • x³ -2x² - 15x

Step-by-step explanation:

#1) Find the polynomial with roots at 2 and 6

  • (x -2)(x - 6) = x² - 8x + 12

#2) Find the polynomial with a double root at -3 and another root at 4

  • (x+3)(x+3)(x-4) = (x²+6x+9)(x-4) = x³ + 2x² - 15x - 36

#3) Find the polynomial with roots 0, -3 and 5

  • (x -0)(x+3)(x-5) = x(x²-2x - 15) = x³ -2x² - 15x
