3. Find the answer by MATLAB using the minimum number of parentheses, where x=2, y=3, z=4 a. x+ 2-1 2 x+ y b. y+3z ecos(2x)+1+2x C. In(x+1)+2 1 d. tan' (xtan(x3)) -X+ x-4yz e. 2y f. cos(2x+1)+2 3x-4 2y sin (0.1z) 1. Use the help function to find out what does the following function do. a. fix, floor, ceil, round, mod, rem b. C. - Please summarize and describe how each function works For what range of values is the round equivalent to floor and ceil? Determine the difference between rem and mod 2. Is fix(-3.2) the same as floor(-3.2) and/or ceil(-3.2)?
