Answer:
x = 0, π/4, π, 7π/4
Step-by-step explanation:
sin(2x) = √2 sin x
Use double angle formula.
2 sin x cos x = √2 sin x
Move everything to one side.
2 sin x cos x − √2 sin x = 0
Factor.
sin x (2 cos x − √2) = 0
Solve.
sin x = 0, cos x = ½√2
x = 0, π/4, π, 7π/4
Answer:The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Combine 23 2 3 and x x . Rewrite in slope-intercept form. Use the slope-intercept form to find the slope and y-intercept.

Answer:
dy/dx = (cos y + y sin x) / (cos x + x sin y)
Step-by-step explanation:
y cos x = x cos y
y (-sin x) + dy/dx cos x = x (-sin y dy/dx) + cos y
-y sin x + dy/dx cos x = -x sin y dy/dx + cos y
dy/dx (cos x + x sin y) = cos y + y sin x
dy/dx = (cos y + y sin x) / (cos x + x sin y)
Answer:
Rs. 144
Step-by-step explanation:
To what the cost of each pen, divide 90/5
You get 18. So each pen costs 18.
Now multiply 18 by 8 and you would get 144.
So, it would cost Rs. 144
Answer:
6
Step-by-step explanation:
The 4 and 12 are multiplied together which creates 48 (4*12). Then you divide the 48 by 8 (48/8) wich equals 6.
