Question

k =sin? b +cos 1 = c(magnitude of complex number c) _log(asin b) +ln(bsina)

a=15

b=pi

c=e^(i)(pi)

how do I write these functions as a command in MatLab?

Answer 1

MATLAB functions used and their explanations

abs: to evaluate absolute value
in matlab log means ln and log10 mean snatural logaritham log.
sqrt: sqaure root
in matlab sin(x) expression x will be taken in radians. sind(x) in this x will be taken in degrees

given expressions in matlab

first assign the given a,b and c values

a=15;

b=pi;
c=exp(i*pi);

now type following lines of code one by one

k=sin(b)^2+cos(b)^2

l=abs(c)

m=(log10(a*sin(b))+log(b*sin(a)))/sqrt(l)

output:

Command Window >a 15 b-pi C exp (i pi) >>ksin (b) 2+cos ( b) ^2 k= 1 >>1-abs (c) 1 = 1 >> m (log10 (a*sin (b))+log (b*sin (a))) /sqrt (1) m = -14.0215
