Sin x+sin 5x= cot 2x​
butalik [34]

Step-by-step explanation:

  1. sinx+sin(x+4x) =cot2x
  2. sinx+sinx cos4x+cosx sin4x=cot2x

sinx+sinx cos4x=sinx (1+cos4x) =

sinx (1-1+2(cos2x)^2) =2sinx (cos2x)^2

sin4x=2sin2xcos2x

2sinx(cos2x)^2+cosx+2sin2xcos2x=cot2x

2sinxcos2x(cos2x+2(cosx)^2)=cot2x

but 2(cosx)^2=cos2x+1

2sinxcos2x(cos2x+cos2x+1)=cos2x/sin2x

(2sinxsin2x)(2cos2x+1) =1

(4cosx(sinx)^2)(2cos2x+1) =1

Please help it’s the last question
Mrac [35]

Answer:

y= -\frac{5}{6}x - 1 is the answer

Step-by-step explanation:

Equation of the line: y = 6/5x + 1

                        = 5y = 6x + 5

                        = 6x - 5y + 5

Equation of the perpendicular line: bx - ay + k = 0

                                                       = -5x -6y + k = 0

Equation passes through (6,-6),

-5(6) -6(-6) + k = 0

-30 + 36 + k = 0

6 + k = 0

k = -6

Substituting,

-5x -6y + k = 0

-5x -6y -6 = 0

-6y = 5x + 6

y= -\frac{5}{6}x - 1 (Slope-Intercept form)
