Problem 2. In this problem, we will use Euler's formula to derive some trigonometric identities. (a) Using Euler's formula and the property that ez+w = e ew for any complex numbers z and | W, show that cost + sin? t = 1. (Hint: Start with 1 = eit-it.) (b) Similarly, show that cos(2t) = cos? t – sint. (Hint: Start with cos(2t) = Re(ezit).) (c) Similarly, show that sin(2t) = 2 sint cost. (d) Similary, show that cos(3t) =...
Can you do part A through B please? 2 Euler's formula relates the complex exponential to trigonometric functions as e" = cos(9) + j sin(9) This problem considers two alternate forms of Euler's formula. (a) Show that we can represent cos(0) in terms of complex exponentials as eje +e-je cos(e) (b) Derive a similar expression to part (a) for sin(e) (c) Use the results of part (a) to hand com pute cos(2). Verify your result with MATLAB. This result conflicts...
On the last homework, we used the angle sum identity to simplify sin(0+7) and cos(0+t). Simplify the expressions cos(T0) and sin(T0) using the angle sum identities again. Then plot the point (cos(T0), sin(T+ 0)) on the unit circle. Why do your answers from the angle sum identity make sense? (cos(0), sin(0)
5. In this problem we will derive some trigonometric identities important for deriving Fourier series. Let wo = 7, where T is a given constant. Assume k, n, m > 0 are integers. 27 (a) Show that T/2 T when k = 0 ejkwot dt =. J-T/2 O when k >1 (b) Use the above result, ej(n-m)wot = ejnwote-jmwot, ej(n+m)wot = ejnwotejmwot, and Euler's identi- ties to deduce (T/2 when n = m, n = 0, m = 0 i....
a) In lecture we derived the estimate of B in WLS as Derive A.wls when p-1. (It should have a form similar to simple linear regression.) (Hints: Notice that we can write a weighted average as analogues of the sums of squares identities we've used; you should derive these if you need to use them.) . You may need to use weighted b) Assume we have the following data: T1 T2 y2 That is, we have a total of n...
i need help with these 3 homework problems, thank you ! Solve a Triangle Using the Law of Sincs (SSA) Ambiguous Case Suppose that the measure of angle A and the lengths of sides a and b of a triangle are given. Depending on the length of side a (shown in red) relative to the length of the altitude h, we have four different scenarios No triangle One right triangle One oblique triangle Two triangles: One acute and one obtuse...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
