Find the Laplace Transform of the following function. <br><br> f(t) = 10 cos (12t+ 60°) u(t)

allsm [11]

Answer:

L(f(t)) = $\frac{5s - 60\sqrt{3} }{s^2 + 144}$

Step-by-step explanation:

f ( t ) = 10 cos ( 12t + 60°) u(t)

attached below is a detailed solution of the given problem

L(f(t)) = $\frac{5s - 60\sqrt{3} }{s^2 + 144}$

A linear equation is shown below.

Stella [2.4K]

You should first of all distribute and combine like terms on both sides. You should subtract 6x from both sides. Once you have done that, you should add 80 to both sides and divide by 6 to get your answer as a simplified fraction of x=-2/3. The correct answer is b.

Lim<br> t—>0 1-cos(2t) / sin^2 (11t)

Nitella [24]

Answer:

2/121

Step-by-step explanation:

Hello,

Hôpital's rule will help here.

$\forall t \in \mathbb{R}^*\\\\f(t)=1-cos(2t)\text{ *** f is differentiable}\\f'(t)=2sin(2t)\\f''(t)=4cost(2t)\\f''(0)=4 \\ \\g(t)=sin^2(11t)\text{ *** g is differentiable}\\g'(t)=2sin(11t)\times 11 \times cos(11t)=2\times 11 sin(11t)cos(11t)\\\\g''(t)=2\times 11 (11cos^2(11t)-11sin^2(11t))\\g''(0)=2\times 11^2$

So the limit is 4/(2*121)=2/121

Thanks
