Answer:
Step-by-step explanation:
Given:
x = 2cost,
t = (1/2)arccosx
y = 2sint
dy/dx = dy/dt . dt/dx
dy/dt = 2cost
dt/dx = -1/√(1 - x²)
dy/dx = -2cost/√(1 - x²)
Differentiate again to obtain d²y/dx²
d²y/dx² = 2sint/√(1 - x²) - 2xcost/(1 - x²)^(-3/2)
At t = π/4, we have
(√2)/√(1 - x²) - (√2)x(1 - x²)^(3/2)
Answer: 0.01 x 10 = .1
it moved ten spaces up or in simpler terms the decimal move one space to the right because the number is getting bigger.
Step-by-step explanation:
The inverse is (x-2)/3 so the answer is f(x)=0
Answer:
5
Step-by-step explanation:
5x -6 = 2x +9
5x -2x = 9 +6
3x = 15
x = 5
the area would be 4 times more
so 135 x 4 = 540
