Derive formulas for radial visualization of(a) 3 - d samples(b) 8 - d samples(c) using the formulas derived in (a) represent samples (2, 8, 3) and (8, 0, ) using the formulas derived in (b) represent samples (2, 8, 3, 0, 7, 0, 0, 0) and (8, 8, 0, 0, 0, 0, 0, 0).

6. write a user-defined matlab function for the following math function: r() = 4cos(4sin ) the input to the function is  (in radians) and the output is r. write the function such that  can be a vector. a) use the function to calculate r(/6) and r(5/6). b) use the function to plot (polar plot) r() for 0 ≤  ≤ 2. hint: use “ polar” and/or for “polar plot in matlab." include the title “'r(\theta)=4cos(4sin(\theta))”
