Q2:-Solve this equation by using matlab without find value.
Equation = (3x$^3$-5x$^2$+2x-12)
Q3:-(A) is matrix in period (1:5:27) arrange them perpendicular and then
find:- diag(A), sum(A), size(A), (A.^2). Note: You could make matrix of
(2*3).
Q4:-The steady-state current (I) Flowing in a circuit that contains a resistance
R=4 Capacities C=3, and inductance L=8 in series is given by :-
I = \frac{E}{\sqrt{R^2+(2\pi WL-\frac{1}{2\pi WC})^2}}
Where E=5 and W=2, write program to calculate and
display the value of (I)?
