Step-by-step explanation:
cot(x) cos(x) + cot(x) = 0
cot(x) (cos(x) + 1) = 0
cot(x) = 0 or cos(x) = -1
cot(x) = 0
x = π/2, 3π/2
x ≠ 0, π
cos(x) = -1
x = π
Therefore, the answer is x = π/2, 3π/2.
⁻⁻Using Sine ratio: opposite / Hypotenuse
Opposite to angle A = 24, Hypotenuse = 25
Sin A = 24 / 25
Sin A = 0.96
A = Sin⁻¹(0.96) Use a calculator.
A ≈73.74°
A ≈ 73.7°
∠A + ∠B = 90° Since it is a right angled triangle.
∠B = 90° - ∠A
∠B = 90° - 73.7°
∠B = 16.3°
Answer:
(c.) m∠A ≈ 73.7°, m∠B ≈ 16.3°, m∠C = 90°
Answer: what are the choices?
Step-by-step explanation:
Answer:
390, since the answer I got was 377, and we are estimating so that’s the best estimate.
Answer:
The two solutions are given as and
Step-by-step explanation:
As the given equation is
So the corresponding equation is given as
Solving this equation yields the value of m as
Now the equation is given as
Here m1=-8, m2=1 so
The derivative is given as
Now for the first case y(t=0)=1, y'(t=0)=0
So the two equation of co-efficient are given as
Solving the equation yield
So the function is given as
Now for the second case y(t=0)=0, y'(t=0)=1
So the two equation of co-efficient are given as
Solving the equation yield
So the function is given as
So the two solutions are given as and
