I need an expert mathematical solution. The radiation intensity of an aperture antenna, mounted on an infinite ground plane with perpendicular to the aperture. is rotationally symmetric (not a function of 4), and it is given by sin (7 sin 0) U π sin Find the approximate directivity (dimensionless and in dB) using

Waveforms v1(t) and v2(t) are given by:v1(t) = −4 sin(6π ×10^4t +30◦) V,v2(t) = 2cos(6π ×10^4t −30◦) V.Does v2(t) lead or lag v1(t), and by what phase angle?

3. Consider the RC circuit with a constant voltage source shown in the diagram below. The values of the resistor, capacitor, and input voltage are R = 50, C = 10 µF, and V = 6V, respectively. Assume that there is initially no charge on the capacitor before the switch is closed. Vo ↑i(t) R w C When the switch closes at time t = 0, the current begins to flow as a function of time according to the equation i(t) = ioenc
