  If V1(t)=sin(2000Πt), What is output voltage at t=3ms? C=1uF and R=1kΩ

1. What is the next root of x₁ given the following

a. The angle line tangent to the function f(x) makes at x = 3 is 57^o with respect to the x-axisb. The initial estimate of the root is x_o  = 3, f(3) = 5.           Root equation is f(x) = 0 and solve it using Newton-Raphson Method

1. What is the second iterative value of the root of te^-t – 0.3 = 0 using the bisection method, given an initial value of [1,5].
2. What is the absolute relative approximate error at the end of the iteration, given that the beginning of an iteration is the lower and upper guesses of the root are x_l and x_u. use bisection method to find the root of f(x) = 0.
3. Solve the square root of R from the equation x² – R = 0, using the Newton-Raphson Method.

An Educational Institute requires a library management system and has contacted your firm. You have 25 programmers, out of which 18 are busy with other projects for the time being. The Institute intends to acquire library books and other equipment, which they want to interface with the computer system. The annual evaluation of the Institute is due soon, in which computerization initiatives are appreciated. (i) Create the process model that you think will be most appropriate for the following situation. Also, list your reasons for choosing the process model and any assumptions that you make. (ii) Assess three reasons not to choose Spiral Model (iii) Outline three reasons not to choose RAD Model

1. Find the magnitude of two like parallel forces acting at a distance of 240 mm, whose resultant is 200 N, and its line of action is at a distance of 60 mm from one of the forces.?
2. ABCD is rectangle, in which AB = CD = 100 mm and BC = DA = 80 mm. Forces of 100 N each act along AB and CD and forces of 50 N each at along BC and DA. Find the resultant moment of the two couples.?
3. Two men carry a weight of 2 kN by means of two ropes fixed to the weight. One rope is inclined at 45° and the other at 30° with their vertices. Find the tension in each rope.
