Elementry mathematical computations using MATLAB? Try these five:

1.      Perform the following calculations in MATLAB, taking variables x = 100 and y = 50:

a.       z = x/y;  b. u = x*y; c. v = x+y; d. r  = √x/y; e. t = √x*y; f. q = x sin(5y).

2.      Taking x = 2.10101 and y = 4.3457, estimate the following expressions in MATLAB:

a.       5x/3y;  b. 45x^-8/y^-7;  c. x^-3-y^-4;  d. x^6.7/(4x+y^-3.1)²

     

3.      Using MATLAB calculate:

a.       e^(-1.3)3+ 16 sin(40π); b. π log 21 + ⁵√291; c. sin² 16π/40 + cos² 16π/40;

d. tan (4π/5)²; e. tan^-10.5².

4.      Take variables x = 6 + 7i and y = -5+ 3i. Estimate with the help of MATLAB:

a.       x + y;     b. xy;      c. x/y;          d. x² + y².

5.      Construct a circuit for analyzing the waveform of a sine wave source using a scope in SIMULINK? Take the source frequency as 50 Hz, 60 Hz, 80 Hz & 100 Hz and verify it on the scope by viewing it’s time period?
