You work as a technical engineer in a company that designs and installs 4G and LTE [wireless cellu networks] solutions for mobile networks like Zain, Orange and Umniah. Your role includes design and optimizing new communications solutions, which requires a good knowledge in sinusoidal sign and their properties. Throughout a new project, your manager has requested your feedback on following cases. Task 1: An alternating current in a 4G signal transmitter is expressed as 1 = 5 sin(120nt + 0.52), I in mA, t in s Find: A. The amplitude, period, frequency and phase shift (phase at time = 0, in degrees) of I B. The value of the current I at: i. t = 0 ii. t = 1/60 What do you notice about your results? C. If the phase of the current I is 1 radians, what is the time at this instance. D. Use MATLAB to plot I for 1 complete period ONLY. E. On the graph, show the point at which the phase of the current I is 1 radian. F. Showing your calculations, find the time at which the current is maximum and positive [hi function is maximum when the angle is t/2 radians, or you can derive and equate to zero!]. iii. t = 1/30 iv. t = 1/15 M .n G. From your plot, find the time, t, yhen current, I is maximum.

Quadratic Equation
When it comes to the concept of polynomial equations, quadratic equations can be said to be a special case. What does solving a quadratic equation mean? We will understand the quadratics and their types once we are familiar with the polynomial equations and their types.
Demand and Supply Function
The concept of demand and supply is important for various factors. One of them is studying and evaluating the condition of an economy within a given period of time. The analysis or evaluation of the demand side factors are important for the suppliers to understand the consumer behavior. The evaluation of supply side factors is important for the consumers in order to understand that what kind of combination of goods or what kind of goods and services he or she should consume in order to maximize his utility and minimize the cost. Therefore, in microeconomics both of these concepts are extremely important in order to have an idea that what exactly is going on in the economy.
