Write a new script for each of the following exercises. 1. Create a vector named cVec that stores the values of the following function: f(x)=0.1excosx+2lnx at x=3,3.1,3.2,,6. Find its summation and print it. The output of the print function must look like: "The sum of this vector is: 256.6346 " Plot the vector using plot () function and add the title of this plot: "My First Plot". Note: the function cos() takes angels in radians. 2. Calculate the following: i=125(i2i+i23i) Print the value of this summation as follows: "The sum of this summation is: 2129170437
