1+sinx+cosx/1+sinx-cosx=1+cosx/sinx help pls by proving
Monica [59]

Answer:

Below.

Step-by-step explanation:

I'll  write sin x as s and cos x as c so we have:

(1 + s +c)/(1 + s - c) = (1 + c)/s

Cross multiplying:

s + s^2 + cs  = 1 + s - c + c + cs - c^2

s  + s^2 + cs = 1 + s + cs - c^2

s^2 + c^2 + s - s + cs - cs = 1

s^2 + c^2 = 1.

- that is sin^2 x + cos^2 x = 1 which is a known identity.

Therefore the original identity is proved.

Ive been waiting hours for someone to answer this question. Is everyone an idiot.
stepan [7]

Answer:

D) x = -2/3 and x = 6

Step-by-step explanation:

4(x²−x+2)−(x+10)(x+2)           Distribute

(4)(x²) + (4)(−x) + (4)(2) + − x² + −12x + −20    Multiply

4x² + −4x + 8 + −x² + −12x + −20           Combine like terms            

(4x² + −x²) + (−4x + −12x) + (8 + −20)      Combine like terms

3x² −16x −12 = 0      

x = -2/3 and x = 6

I graphed the equation on the graph below.
