World wind energy generating1 capacity, W, was 371 gigawatts by the end of 2014 and has been increasing at a continuous rate of approximately 16.8% per year. Assume this rate continues.  (Generating capacity is the maximum amount of power generated per unit time.) (a)  Give a formula for W, in gigawatts, as a function of time, t, in years since the end of 2014. W=371e^(0.168t) gigawatts (b)  When is wind capacity predicted to pass 700 gigawatts? Wind capacity will pass 700 gigawatts during the year

Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.
