If you put a pendulum under the influence of a flow, a drag force will move the pendulum creating an angle with respect to the vertical. As the angle is related to the drag force, and because the drag force is related to the velocity of the flow, you can determine the velocity of the flow by only measuring the ang...

The function is defined if... (e^( cos^(-1) (log x^2) ))^1/2 The base of log is 4 $f(x) = \sqrt{e^{\arccos{[\log{(x^2)}]}}}$. Note that the logarithm is only defined for $x > 0$. Since $x^2 \geq 0$, we can already see that we can not let $x = 0$. Also note that $\arccos{x}$ is only defined for $-1 \leq x \leq 1$. The ...

Math Help The answers are all here. If $f(t) = t^n$ then $\mathcal{L}(f)(s) = \frac{n!}{s^{n+1}}$. So the Laplace transform of $6t^3$ is $\frac{36}{s^4}$. Also, the Laplace transform converts convolution products to regular products. So $\mathcal{L}((f*f)(t)) = (\mathcal{L}(f)(s))^2$. Therefore $(\mathcal{L}(f)(s))^2 ...
