Is this correct for part A.

x = -pi:0.01:pi; plot(x,sin(x)), grid on 

x = [-i pi+i*pi/2 -1+i*4]; y = sin(x) 

b) function h = circle(x,y,r) 

hold on 

th = 0:pi/50:2*pi; 

xunit = r * cos(th) + x; 

yunit = r * sin(th) + y; 

h= plot(xunit, yunit); 

S = 1/(12*s); 

P = vpa(S,d); 

hold off 

PLease read the additional information. Parts b and C.

3. (90 points) For sin(x) and cos(x): a. Reduce the argument x, which originally can take the range of (-oo,+oo) to [0, 2T) using the modulo operator (b mod (a,m)). b. Further reduce the argument from part (a) to [0, TU/2) using relationships for sin(x) and cos(x) in the different quadrants of the circle. c. Call a sub-function to compute the value of the new, reduced argument from (a) and (b) above. The minimum argument value will be 0 and maximum will be t/2. 3. (90 points) For sin(x) and cos(x): a.
