The maximum of \( \sin\left(\frac{\pi x}{r}\right) \) is 1, occurring when \( \frac{\pi x}{r} = \frac{\pi}{2} + 2k\pi \), e.g., \( x = \frac{r}{2} \).The maximum of \( \cos\left(\frac{\pi y}{r}\right) \) is 1, occurring when \( \frac{\pi y}{r} = 2m\pi \), e.g., \( y = 0 \).Thus, the maximum value of \( f(x, y) \) is:+ 1 = 2This maximum is attainable within the field, for example at \( (x, y) = \left(\frac{r}{2}, 0\right) \).Therefore, the maximum nutrient concentration is:Question:** An electrical engineer analyzes the magnetic flux through a coil whose area vector \( \vec{A} \) rotates in the \( xy \)-plane. If \( \vec{A}(t) = A_0 \cos(\omega t) \hat{\mathbf{x}} + A_0 \sin(\omega t) \hat{\mathbf{y}} \) and the magnetic field is \( \vec{B} = B_0 \hat{\mathbf{z}} \), compute the time average of the magnetic flux \( \Phi_B = \vec{B} \cdot \vec{A}(t) \) over one period.The magnetic flux is:\Phi_B(t) = \vec{B} \cdot \vec{A}(t) = B_0 \hat{\mathbf{z}} \cdot \left( A_0 \cos(\omega t) \hat{\mathbf{x}} + A_0 \sin(\omega t) \hat{\mathbf{y}} \right) = 0since \( \hat{\mathbf{z}} \) is perpendicular to both \( \hat{\mathbf{x}} \) and \( \hat{\mathbf{y}} \), and the dot product with zero components is zero.
