The solution is you need to subtract the y axis and x axis
according to the picture we have:
x.y=4.7
(7)x(7)y=49xy=(49)(4.7)=230.3
I'll write "x" instead theta.
sin x + 1 = cos(2x)
formula: cos(2x) = 1 - 2sin²x
sin x + 1 = 1 - 2sin²x
2sin²x + sin x = 0
sin x (2sin x + 1) = 0
sin x = 0 or sin x = -1/2
x1 = πk and x2 = -π/6 + 2πk and
x3 = 5π/6 + 2πk
for domain 0≤x<2π :
x1 = 0 (for k=0 in x1)
x2 = π (for k=1 in x1
x3 = 11π/6 (for k=1 in x2)
x4 = 5π/6 (for k=0 in x3).
k is an integral.
Answer: y3−1y3=234
Step-by-step explanation:
y−1y=6
(y−1y)3=63
y3−3y+3y−1y3=216
y3−1y3=216+3(y−1y)=216+3(6)
not sure:)
The answer to the problem is D.61/100
Hope this helps.
